[[caption-width-right:320:You... um... ''really'' wouldn't guess based on one look at her that she plays an eleven year old girl. [[note]]To be fair, Maisie was a few years younger when Arya was eleven.[[/note]]]]
Margaret Constance "Maisie" Williams (born April 15, 1997) is a British actress. Her first role outside of school theater has been as Arya Stark on the {{Creator/HBO}} series ''Series/GameOfThrones''. Her standout performance has received considerable acclaim, especially in light of her rather short resume, mixed with the extremely heavy material and experienced actors she's had to work with. In March 2013, it was announced she will star in the upcoming SciFi ActionAdventure movie ''We Are Monsters''. She also was in ''Film/Cyberbully2015''. She was also announced to play the lead role in the indie silent film ''Corvidae'' ([[http://www.indiegogo.com/projects/corvidae-short-film-starring-maisie-williams look at its indiegogo entry here]]) and is rumored to be playing Ellie in a live-action film of ''VideoGame/TheLastOfUs''.

In 2015 she had a recurring role in Series 9 of ''Series/DoctorWho'' as Ashildr (AKA "Me"), a girl from a Viking village. She's appeared as Lucy in TheFilmOfTheBook of ''Literature/IBoy'' in 2017. In 2018, she had a voice role in the animated film ''WesternAnimation/EarlyMan''. She's also set to star as Wolfsbane in 2019's ''Film/TheNewMutants'', based on the Creator/MarvelComics [[ComicBook/NewMutants of the same name]].

* BigGuyLittleGuy: The little gal to her close friend Creator/SophieTurner. It helps that they're the same age.
* CastIncest: Maisie and [[Creator/SophieTurner Sophie "Sansa" Turner]] play this for laughs by joking about shipping themselves and sometimes groping each other in public.
* DawsonCasting: Starting in season 4, once Maisie hit puberty.
* DyeingForYourArt: She got her hair cut short for the show's second season. She also learned to use a sword with her left hand, as Arya is a leftie (Maisie herself is right-handed). The producers offered to make Arya right-handed in the show, but Maisie herself insisted she remain a leftie, knowing how much the fans would want to see it.
* OneOfUs: After participating in a ''Series/GameOfThrones'' panel at the 2014 San Diego Comic-Con, she later joined the crowd at Comic-Con, wearing a ComicBook/SpiderMan mask [[http://www.buzzfeed.com/elliewoodward/maisie-williams-managed-to-go-unnoticed-at-comic-con-thanks#4bx3ssm so she could tour the convention floor without being recognized.]] She's also a fan of LetsPlay/HatFilms, [[https://twitter.com/maisie_williams/status/373635764644376577 as seen here]], which caused the trio to freak out quite a bit.
* ReclusiveArtist: She is determined to keep her personal life as private as possible. She stated from the start that her Youtube channel would rarely be updated, and while she posts fairly regularly on Twitter and Instagram, she's only shared a few intimate details. She's revealed (in seperate interviews) both that she'd lost her virginity and had a boyfriend, but has only said that he's not in show business and refuses to tell his name.
* ShipperOnDeck: Supports Arya/Gendry, although that's mostly because she has a crush on Joe Dempsie, who plays Gendry.
* ShesAllGrownUp: Look at the first episode of the show, [[MsFanservice and then look at her pictures on her Instagram account]].
* SuppressedMammaries: She's about 4-5 years older than her character in ''Series/GameOfThrones'', and thus is padded down to look younger. Compare pictures of her in the show with those of her at the premieres or conventions.
