Mariana Adams Foster (born Mariana Gutierrez) is a main character on the The Fosters. She is the daughter of Ana Gutierrez and Gabriel Duncroft, the adoptive daughter of Stef Adams Foster and Lena Adams Foster, the fraternal twin sister of Jesus Adams Foster, and the adoptive sister of Brandon Foster, Callie Adams Foster, and Jude Adams Foster.
Mariana is portrayed by actress and singer, Cierra Ramirez.
Mariana was born May 17, 1998  and is the twin of Jesus Adams Foster. Her birth mother is Ana Gutierrez while the identity of her father is unknown. It is estimated that she and her brother were with her drug addicted mother until they were around 5 years old before being put into the foster system when Ana finally abandoned them altogether.
While the time period they were the foster system is unknown, although likely around a year or so, Mariana does recall being a foster kid. She laments to Callie in one episode how she remembers the frequent moving around, various girls she had to room with, and sometimes being put into some "messed up" homes. Mariana also says that she had a hard time truly trusting anybody as a result of being in the system; she didn't feel true love and safety until Stef and Lena took her and Jesus in.
Mariana is a young, beautiful girl with a pale complexion, dark brown eyes. She has medium length deep brown hair which she wears in a variety of styles: curly, straight, or naturally waved. She has a slim, yet toned and athletic figure. Mariana's clothing sense is very girly; she often wears bright colors, such as pinks, yellows and blues. She is often seen wearing a mixture of floral dresses and skirts with colorful cardigans and heels, and dark jeans and jackets over bright colored shirts.
Mariana is very smart and girly and cares about appearances, in the least hers, very much. She's shown to be popular and is always organizing social events. Frequently, Mariana has shown strong leadership among her peers and is very proactive during a variety of situations, even organizing a protest against Mr. Timothy's firing at Anchor Beach. Not unlike the rest of her siblings, Mariana is extremely loyal and protective over her family and friends.
While she is usually kind, she can be naive when it comes to certain topics. However, she usually learns from her mistakes. Mariana also loves to gossip and speaks Spanish fluently. Despite her confident exterior, underneath it all she can be very insecure and sometimes caves into peer pressure in order to be accepted. This is shown multiple times throughout the series. For example, when seeing old friend Garret had a new edgier scene and friends, she pierced her nose herself at home to fit in. Also, when making it onto the dance team, she had overheard fellow dance teammates claiming she only made the cut because she's Latina - this leading her to dye her hair blonde to fit in with their crowd and distance herself from her Latin heritage. However, she has learned not to give into how others make her feel and to be herself.
Callie catches Mariana stealing pills from Jesus. It is later revealed when Jesus discovers a large amount of cash, that Mariana was selling the pills because Ana needed money. Jesus gets mad at her, reminding her that Ana abandoned the twins so she could run off with a "dumbass" and screw whoever she wanted while he was holding a picture of them and ripped it in half. Mariana tearfully tells him that Ana has come back to town. Mariana fakes a stomach ache in order to sneak out and meet Ana, whom she has been chatting with online. They finally meet, but it is not what Mariana was expecting. Ana takes the money and leaves suddenly. Mariana is devastated and goes home.
Mariana is blamed for reading Callie's journal. Mariana told Callie she didn't do it and knows that Callie doesn't trust her. Then, she explains to Callie the reason behind her selling Jesus' pills.
Mariana prepares for her Quinceañera and asks Callie to take Kelsey's place in her court. Callie agrees to do so. Mariana also asks Mike to do the traditional father/daughter dance with her because she is a little embarrassed of having two moms.
During the Quinceanera Mariana finds out about Jesus and Lexi's relationship and is not happy. Mariana tells Jesus she knows about the relationship. Lexi tries to talk to Mariana in the bathroom but gets the cold shoulder. Mariana ends up dancing with Mike instead of with her moms.
Lena and her mom have a disagreement. Lena's mom thinks that Mariana shouldn't have had this party and thinks just because she is Latina doesn't mean she's Latina. Lexi insists on leaving but Jesus stops her and says it's his birthday too and that he wants at least one dance with her.
They have cake and have a family photo including Callie and Jude. They show a slideshow of Jesus and Mariana. During the slideshow it shows some pictures of Mariana and Lexi. Mariana smiles at her. Mariana tells Lena and Stef that she is acting selfish (because Jesus said she was being selfish because they raised her and gave her this party and she won't dance with them) and says sorry to her moms. Her moms disagree and say she is wonderful. At the end no one saw but she did dance with them.
At breakfast, Mariana rebuffs Jesus' wanting to go to a church camp for the weekend with Lexi, and questions his religious beliefs; "Since when are you religious?" Later, Mariana meets with her birth mother, Ana, instead of seeing Garret like she told Lena. They discuss her Quinceañera and Ana even gives her a gift. Back at home, Callie and Mariana discuss Wyatt's party, and Mariana suggests that they should go. Callie reluctantly agrees before they tell the moms that they are going to Wyatt's to watch a movie. At the party, Mariana runs into Kelsey who lets slip that Jesus and Lexi had unprotected sex. Mariana, angry and upset, gets drunk and Callie decides it's time to leave. When Mariana and Callie arrive back home, Mariana makes a scene in front of the dinner party and tells Lexi's parents that Jesus and Lexi had sex. Angry, Stef and Lena put Mariana to bed.
Mariana and Jesus are fighting over the fact that Mariana told Lexi's parents that he and Lexi had sex. Stef ends the fight and tells Mariana that she brought it upon herself. Because of what Mariana did, Lexi's parents refuse to let Jesus date their daughter and have decided to send Lexi to a boarding school. Feeling guilty, Mariana helps Lexi hideout from her parents after running away. While helping Lexi, the girls talk and reconnect. After finding out from Jesus that Lexi and her parents are not legal U.S. citizens, Mariana reveals where Lexi is staying.
Mariana tells Callie that she wants Liam put away for his crimes. After class, Lexi reveals to Mariana that it's definite that she'll move to Honduras. Mariana promises to Lexi that she won't tell Jesus, but she ends up telling him anyway. Mariana removes her nose piercing for her moms to please them. Mariana dances with her family. She is asleep when Callie runs away.
Mariana and Jesus get into an argument about who gets to spend time with Lexi before she leaves for Honduras. Jesus enters Mariana's room while her and Lexi are working on their English assignment. He asks for time alone with his girlfriend, but Lexi lets him go after feeling she is letting her best friend down. She tells her that it is complicated when you are in love, and that she will understand once she has a boyfriend. Mariana is left angered by this. Jude rushes into Callie and Mariana's bedroom checking her closet and her drawers only to find out that it's empty. The family have a family meeting discussing about Callie. Brandon asks Mariana if she thinks Callie is back with Wyatt. She says that she doesn't think as she thinks they broke up a month ago. Brandon doesn't understand why Callie would take off. Mariana says that finally felt like she had a sister. They realize they are late for school until Stef's car won't start. At school, Mr. Timothy tells Mariana that she will need a new partner. She now finds out that Lexi is leaving for Honduras and not returning.
Marianna and Jesus confront Brandon about kissing Callie. Marianna says he is going to tear the family apart. She leaves, and Jesus tells Brandon that he agrees with Marianna. Marianna is recruited by a cute senior named Chase to audition for the school play. Marianna shows up to audition for the school play. She is greeted by Zac, who is a designer for the play. He is unimpressed with Chase, unlike Marianna. He pairs Marianna and Kelsey together to work on costumes. Marianna and Kelsey argue over working with each other. Marianna and Kelsey shop for costumes for the play, but Marianna is nervous that Kelsey will shoplift. While Marianna is trying on a dress, Kelsey shares that she thinks Chase is “hot.” When the girls leave the store, they are stopped by a security guard who wants to check their bags. Kelsey looks nervous. Marianna confronts Kelsey about the hat when Chase appears and spots the hat. He is impressed and says it defines his character. He thanks Marianna for the hat and walks off. Kelsey smiles and tells Marianna she can thank her later.
Mariana takes a liking to Chase and agrees to help him run lines after school. This angers Kelsey, so Mariana decides that neither of them should be with Chase if it means ruining their friendship, so she cancels reading lines with him, but to her surprise Kelsey offers to read lines with him instead. When Kelsey gets detention, Mariana goes to read lines with Chase, and they end up kissing. Kelsey sees this and out of anger, she tells the principal that Mariana was the one who was selling her drugs, getting Mariana suspended.
Mariana is seen get along with the girls for the United Girls home.
Padre Mariana finally thought she was going to get a sister and then Callie ran away. And top of that her best friend moved thousands of miles away and she lost Jesus as well. Her twin is too focused on juggling his relationship with his girlfriend and very good friend, Emma. Maybe that’s why Mariana asked Brandon if he was the reason Callie wasn’t staying.

In the hallway at school, Marianna sees Zac’s mom who is going to volunteer at the school dance. Zach approaches both of them. When his mom leaves, he and Marianna are talking and it is clear that Marianna wants Zach to ask her to the dance, but he appears to be afraid and chickens out.

Main article: Matiana
Matt is a member of Brandon's band. This is how Mariana originally got to know him. The two initially bantered often, and as the two grew close, Matt, after asking for Brandon's permission, asked her out, to which she accepted. The two connected over having biological parents abandoning them and the uncomfortableness of letting someone know. Things are going good with them until Mat informs Mariana that his band, Someone's Little Sister, is going on tour for three weeks in the beginning of the summer. Upset that he'll be gone for so long, she initially pushes him away, before they talk it out, and Mat and Mariana then say "I love you" for the first time in Light of Day. Mariana plans on having sex with Mat in Wreckage before he goes on his tour, so he has something to remember her by. Mat rejects her, however, wanting their first time to be somewhere special. After he leaves her, Mariana, believing he rejected her so he can have sex with other girls on tour, drinks and has sex with Wyatt. She immediately regrets the decision.
They break up in More Than Words after Mat drives back down to visit Mariana. He apologizes for leaving her like he did, and says that he'd like to have sex with her while he's back, if she still wants to. Mariana, unable to handle the guilt of cheating on him with Wyatt, which Mat was unaware of, and knowing Mat would be spending a large amount of time away on tour, breaks up with Mat. They briefly re-unite in Idyllwild following Brandon's music performance, with Mat claiming that he'll give up the tour to spend the summer with her if it wasn't too late. However, when Mat admits the reason he rejected her the first time was because he was a virgin too and wished for them to lose their virginity together somewhere special, Mariana admits in shame that she had sex with another guy. Mat, heartbroken, refuses to talk to her for some time. In Lucky, in an effort to win him back, Mariana sings a love song to him, but Mat walks away mid performance. Mariana finally confronts him after the performance by saying she knows she made a huge mistake, but has forgiven herself. When Mat says he is glad to hear that, Mariana hopes this means they can date again. However, Mat tells her that while he is glad she has forgiven herself, he is not willing to get back together, and leaves the room, leaving behind a dejected and hurt Mariana.
Mat and Mariana are both later cast as Romeo and Juliet in Mat and Brandon's senior project, R+J. Throughout rehearsing for the show, the two date other people, but are still shown to have feelings for one another. Come opening night, their feelings come to a head and they finally tell each other they still love one another in The Show. Mat had initially left Mariana a letter about it, and how he has forgiven her for the Wyatt incident, but she never got it because her boyfriend, Nick, had intercepted it and destroyed it. They decided to not pursue a relationship initially, because they both didn't want to hurt their significant others. However, after Nick comes to school and then her house with a gun, Mariana's relationship with him effectively ends, and she and Mat get back together in Trust.
Their relationship gets rocky once Mat finds out that Mariana had still been seeing Nick and allowing Nick to believe they were still together, even after she got back together with Mat, and when he found out about her taking her brother's Adderall medication. She soothes his doubts and questions when he confronts her in Dream a Little Dream, and the two end up having sex. But after some questioning from Brandon to Mat on the possibility of Mariana being pregnant, after witnessing Emma buy a pregnancy test and hand the bag off to Mariana, Mat realized that he couldn't trust Mariana again after all the lying she's done to him, and they break up in Cruel and Unusual.
Nick is a guy which Mariana started relationship after dating Mat. At first she thought he is immature, after witnessing his behavior with Jesus in her house and after he participated in a car race while she was in the car. However, after he increased his EQ and apologized, they reconciled and began to date. During their relationship, Nick repeatedly pulls out the big stops for her. This includes lending his father's warehouse for her birthday party and hiring a DJ for the party, lending his father's warehouse again when the play she is in, R+J, can't be held at the high school, and buying her a diamond necklace as a birthday present. Their relationship faces troubles during the production of R+J, when Mariana begins to reconnect with her ex, Mat. Nick is informed that the reason Mariana and Mat broke up was because Mariana cheated on Mat. Initially scared he'd break up with her over finding this out, Nick tells her that it's okay, and that when things get rough for them, she should just tell him, as he would rather be hurt than surprised, which she agrees to. During rehearsals for the show, Mat writes and leaves a note for Mariana in her book bag, stating that he still loves her and wants to know if she does too, and if she would like to get back together. Nick, having witness Mat place the note in her bag, intercepted it before Mariana could see it. During opening night, Nick watches Mat and Mariana perform with a jealous expression, but later congratulates her mid-show on how well she is doing.
A few days after the show, he witnesses Mariana and Mat kiss and hug in the garage. The next day at school, he brings a gun. Mariana and Nick talk at school and she explains that she was only saying goodbye to Mat, but Nick doesn't believe her. Nick, on the loose with a gun, breaks into Mariana's house and sneaks up on Mariana with the gun. Initially pointed at her, he then points the gun to his temple and cries about how he has no-one and no reason to live. A desperate and scared Mariana says he has her, and convinces him to put the gun down by claiming that she loves him and doesn't want him to break her heart by killing himself. It works, and her mother Stef comes in and takes the gun, and Nick is arrested. Under the belief that they are still together, Nick reaches out to Mariana by calling and texting her while he's in a mental facility. Mariana allows him to continue to believe this, despite the fact that she has begun dating Mat again, because he has insisted that she is the only reason he has to live, and is scared of what he'd do if he found out they weren't together anymore. Nick eventually finds out and breaks house arrest to see Mariana, who yells at him about how unsafe he made her feel and how she never wants to see him again in Collateral Damage, to which Nick says he understands they aren't together anymore, and apologizes for how he's made her feel.
- She pierced her nose herself in The Morning After. Although, she takes her stud piercing off before Stef and Lena's wedding in I Do and hasn't been seen wearing it since.
- Mariana sees Ana, her birth mother, for the first time in the Pilot. Mariana had been secretly talking to her online for some time prior to this, deeply wanting to know her birth mother. However, the relationship between the two is strained for a majority of the series, due to Ana's drug addiction, but has improved following her rehabilitation.
- In Vigil, it is shown that Jesus and Mariana were adopted July 1, 2006 by Stef and Lena.
- She dyes her hair blonde in Things Unknown, but soon returns to her natural hair color in Someone's Little Sister.
- In The Honeymoon, Lena states that everyone now has the same last name. In Things Unknown, Mariana's name is shown as "Mariana Adams Foster" on the school dance team roster.
- She was on the original school dance team before creating her own separate team due to differences with the dance team captain, Kaitlyn.
- Mariana can be very sensitive to peer pressure or a lack of social acceptance. This is shown throughout the series; such as when she pierced her nose herself to fit in with her old friend Garret's crowd and dying her hair blonde to also fit in with her original dance team when overhearing them insulting her for, supposedly, only making the team only because she is Latina.
- She wears glasses occasionally while at home, but contacts while in public.
- It is implied that Mariana has abandonment issues, most likely due to her biological mother Ana leaving her and Jesus when they were kids. She was shown to react to the idea of Jesus or Callie leaving the Fosters house very badly. She has also been worried about Stef and Lena not loving her from time to time, usually because she isn't their biological child, often needing to be re-assured that she is loved regardless of her parentage. Another significant example is when her boyfriend Mat leaves for his three week band tour and, in an act of desperation, wished to lose her virginity to him so he could "remember" her. When he turned her down, she instead had sex with Wyatt under the belief that Mat rejected her offer so he could hook up with girls while away. When realizing her error in judgement, she is guilt ridden for her reckless actions.
- Mariana is, at least for a majority of the series, a vegetarian due to knowing about the abuse animals endure while in the process of becoming edible food. She temporarily breaks this diet by eating fish in Mother Nature; however, she says it is strictly because she is in "survival mode".
- She loses her virginity to Wyatt in the season three premiere Wreckage. She originally intended to lose it to her then-boyfriend Mat so that he would "remember" her while on his three week band tour. However, he turned her down and she ran into Wyatt, who she began drinking with before initiating a hook up. This is a choice she deeply regrets since Wyatt is Callie's ex-boyfriend and she feels like she became "that girl who lost it to a guy she barely knows". Mariana even considered dating Wyatt, hoping she could learn to love him, so she could say she lost her virginity to her boyfriend, not an almost stranger.
- Her biological grandmother Elena has stated that Mariana looks a lot like how Ana did as a teenager before she started using drugs.
- Characters have twice expressed a fear of Mariana, both times to Brandon, and both times in response to a suggestion of Brandon's. Mat expresses having a healthy fear of her in If You Only Knew when discussing the idea of prohibiting her from attending the phrarm party. When Brandon asks Callie to wake up a sleeping Mariana in The Show, Callie refers to the act as "unleashing the beast," and that they should be afraid.
- In Not That Kind of Girl, it's revealed that Mariana had to take her driver's test twice. She says the answers were too obvious, and she thought they were trying to trick her.
