Thora Josephine Birch (born March 11, 1982) is an American actress. She made her film debut with a starring role in Purple People Eater (1988) and won a Young Artist Award for "Best Actress Under Nine Years of Age". Birch rose to prominence as a child star during the 1990s through a string of parts in films, such as Paradise (1991), Patriot Games (1992), Hocus Pocus (1993), Monkey Trouble (1994), Now and Then (1995), and Alaska (1996). Her breakthrough into adult-oriented roles came with her portrayal of Jane Burnham in American Beauty (1999), for which she was nominated for the BAFTA for Best Supporting Actress.
Birch received further acclaim—and a Golden Globe nomination for Best Actress—for starring as Enid Coleslaw in the cult hit Ghost World (2001). Her other film credits during the 2000s included Dungeons & Dragons (2000), The Hole (2001), Silver City (2004), and Dark Corners (2006). Birch took a break from acting after producing and starring in Petunia (2012). She returned in 2016 and has since appeared in various independent films, such as The Last Black Man in San Francisco (2019) and The Chronology of Water (2025).
On television, Birch played the title role in Homeless to Harvard: The Liz Murray Story—for which she received an Emmy nomination—and the recurring role of Gamma / Mary on The Walking Dead (2019–2020). She made her directorial debut with the Lifetime film The Gabby Petito Story.

Early life
Birch was born in Los Angeles, California to Jack Birch and Carol Connors, ex-pornographic film actors who both appeared in the 1972 cult classic, Deep Throat. She is of German-Jewish, Italian, Scandinavian, and French-Canadian ancestry. Her forename is derived from that of Norse god of thunder and lightning, "Thor", which would have been her name if she had been born a boy. She has a younger brother, Bolt.
Because of their own experiences with the entertainment industry, Birch's parents were reluctant to encourage her to act, but were persuaded to show Birch's photograph to talent agents by a babysitter who noticed her imitating commercials. Birch got her first big break at the age of four, when the babysitter accompanied her to a successful audition for a Quaker Oats commercial.
Career
1988–1998: Television work and film breakthrough
Birch appeared in commercials in the late 1980s for Burger King, California Raisins, Quaker Oats, and Vlasic Pickles. She made her film debut as Molly Johnson in the 1988 science fiction comedy Purple People Eater, for which she won a Young Artist Award in the category of "Best Young Actress Under Nine Years of Age". That same year, she guest-starred in an episode of Doogie Howser, M.D., and was cast in the regular role of Molly on the NBC sitcom Day By Day. The show ran for two seasons, earning Birch a further two Young Artist nominations.
In 1990, Birch was cast in a principal role on Parenthood, a sitcom based on the 1989 film of the same name, which ran for a single season on NBC. Birch had a supporting role in the 1991 drama Paradise, with Roger Ebert stating in his review for the Chicago Sun-Times that she performed the role with "strong, simple charm". That same year, she starred in the Christmas film All I Want for Christmas, as a girl helping her divorced parents reunite with each other. The film was a moderate financial success, but found an audience on television and home video in subsequent years. Birch played the daughter of Jack Ryan in the spy thriller Patriot Games (1992), a commercial success which grossed US$178 million at the worldwide box office.
At age 11, Birch starred in the Halloween-set fantasy film Hocus Pocus (1993), playing the younger sister of a teenage boy who inadvertently revives a trio of witches. Making US$39 million in the U.S. (against a budget of US$28 million), the film was not considered a financial success upon release, but quickly developed a sizeable cult following due to strong home video sales and television re-runs. "I think the most surreal thing is that it keeps getting more popular instead of the other way around", Birch later said, while admitting the experience was "the most amount of fun I've ever had on a set".
In the 1994 comedy Monkey Trouble, Birch played a girl who befriends a Capuchin monkey. In a positive review for the Austin Chronicle, Marjorie Baumgarten observed that Birch's "nuanced performance (a rarity amongst child performers) no doubt lends [the film] its realistic touch". That same year, she reprised her role in the sequel set after Patriot Games, Clear and Present Danger, which grossed over US$215 million globally. She was then cast as "Teeny" Tercell in the 1995 coming-of-age drama, Now and Then. The film was largely dismissed by critics upon release, but has since been recognised as a milestone of its genre. Next, Birch headlined the adventure film Alaska (1996), playing one of two siblings who cross the Alaskan wilderness in search of their lost father. The Austin Chronicle found it to be a "decent kids' adventure movie" with an "impeccable" performance by Birch. For the next two years, she did not appear on films, but guest-starred in episodes of Promised Land and Touched by an Angel.
1999–2003: Transition to adult roles
Birch appeared in several projects in 1999: firstly, the made-for-television film Night Ride Home, where she played a teenager grieving the loss of her older brother. Writing for Variety, David Kronke called it "a thoughtful and sensitive examination of how a family copes with grief", while saying of the performances, "De Mornay [...] digs deep and comes up with a character that seems true; Burstyn and Birch competently complement [her]". Next, she played the small, uncredited role of Mary in Anywhere but Here.
Birch's portrayal for the insecure teenage daughter in American Beauty, Sam Mendes's dark dramedy about the struggles of a middle-class household, was roundly praised by critics, with Peter Travers of Rolling Stone writing that she "[glimmered] with grown-up radiance". The performance earned her a BAFTA nomination for Best Supporting Actress, while the film was the recipient of the 1999 Academy Award for Best Picture and grossed over US$356 million worldwide, emerging as the biggest commercial success of Birch's career to date. She later said of the experience, "There was a lot of therapy involved [...] A lot of opening up and sharing things from our own lives about why we related to these characters. Everybody brought a lot of themselves to it. I know Annette did a lot of research about women becoming obsessed with the self-help realm. Kevin was working out obsessively and already in the headspace of [his character] Lester, even in rehearsals. And then there was Wes, Mena and I, who were these kids just incredibly excited to be there and watching [these] masters at their craft — just trying to absorb as much as we could from them".
Birch starred in two films released in 2000: low-budget drama The Smokers, in which she was called "a scene-stealer" by The Hollywood Reporter, and Dungeons & Dragons, a poorly-received adaptation of the fantasy role-playing game of the same name. British horror film The Hole came next, where she starred as Liz, a devious schoolgirl who lures a group of her friends into an underground bunker. In a mixed review for Variety, Derek Elley stated that Birch gave "an effectively creepy lead [performance]", but called the film "clunky" in its "attempt to merge the psychothriller and teen movie genres".
Birch's next project was the satirical 2001 comedy Ghost World, directed by Terry Zwigoff. Based on the graphic novel of the same name, the film was released to an enthusiastic critical reception and developed a loyal cult following. James Berardinelli found Birch's part to be her "first effectively developed role" since American Beauty, commending the actress for the "quirkiness [and the] underlying sense of melancholy and ennui" in her portrayal of Enid Coleslaw. Meanwhile, A. O. Scott said in his appraisal for The New York Times:
2004–2012: Independent films
Birch had a supporting role in Silver City, a political satire directed by John Sayles, which premiered at the 2004 Cannes Film Festival. The independent feature received mixed reviews, but Empire's Angie Errigo thought Birch's portrayal of whistleblower Karen Cross was "terrific". She co-starred in the crime drama Slingshot (2005) the following year, with Variety stating that her "standout" performance "commands attention".
In Dark Corners (2006), a psychological horror-thriller about a young woman who wakes up one day as a different person, Birch starred in the dual role of Susan Hamilton and Karen Clarke. The film received a mixed reception, with Adam DiLeo of IGN praising its surreal, David Lynch-style elements, but criticizing Birch's performance. She followed this with roles in two more genre films: Train—a slasher film about a group of college wrestlers who fall victim to a violent gang of thieves, released in 2008—and the psychological thriller Deadline, in which she co-starred with Brittany Murphy, who died shortly after the film's release in December 2009. Birch later revealed she had been concerned about Murphy's wellbeing during filming.
In the true crime drama Winter of Frozen Dreams (2009), Birch played Barbara Hoffman, a Wisconsin prostitute convicted of murder in the first-ever televised murder trial. In a review for Bloody Disgusting, John Marrone described Birch's "alluring" performance as the highlight of the film. Next, she took on the role of journalist Sidney Bloom in The Pregnancy Pact, a Lifetime movie based on the true story of a group of high schoolers in Gloucester, Massachusetts, who plotted to get pregnant at the same time and raise their children communally. The film was watched by 5.9 million viewers when it premiered in January 2010. Later that year, Birch was cast—in what would have been her stage debut—as Lucy in the off-Broadway revival of Hamilton Deane's Dracula, but was subsequently dismissed from the production for the alleged behavior of her father—her manager at the time—who was reported to have physically threatened one of the show's cast members during a rehearsal.
Birch played the role of Vivian in Petunia (2012), an independent dramedy depicting the lives and romantic relationships of a dysfunctional New York family. Her first outing as a producer, she described the "intimate [and] honest" feature as "a little bit different". Given a small theatrical release in the U.S., the film garnered mixed reviews, though Birch and the rest of the ensemble were praised.
2013–present: Break from acting, subsequent return, and directorial debut
After devoting herself to academic pursuits, which included securing a degree in legal studies through Kaplan University, Birch returned to acting in 2015 with a recurring role as software engineer Morgan on the first season of the USA Network sci-fi drama series, Colony. It was later revealed that Birch would not return for the second season because of a scheduling conflict, with the part being recast.
Birch starred as a left-wing activist in the 2018 political thriller Affairs of State, which Noel Murray of The Los Angeles Times called "refreshingly smart". In a less favorable review for Forbes, Luke Y. Thompson wrote, "[cinematographer] Horacio Marquinez gamely films everything like it's an art movie, though there's one scene in which he shoots Birch so unflatteringly that you wonder what she must have done to make him mad". She headlined and co-produced The Competition that same year, an independent romantic comedy.
Next, Birch starred in the 2018 drama The Etruscan Smile—an adaptation of José Luis Sampedro's novel—which was filmed in Scotland and received strong reviews. The following year, she played a supporting role in the crime thriller Above Suspicion, which—after Patriot Games and Clear and Present Danger in the 1990s—marked her third collaboration with director Phillip Noyce. In a positive review for The Guardian, Peter Bradshaw commented, "There's an interesting cameo from Thora Birch [as the] long-suffering Jolene".
Birch's appearance in The Last Black Man in San Francisco (2019), a drama about a young man's pursuit to reclaim the Victorian home built by his grandfather, was considered a crucial part of the film's success. Speaking of her casting and the symbolic nature of the part, director Joe Talbot said:
Thora is one of the great actresses of her generation and her work, in part, inspired me to want to make films. Her performance in Ghost World made me feel seen as a teenager when I was a bit lost. At the end of that film, [she] rides a bus off into the sunset. In our film, we meet her character on a bus in the heart of San Francisco—almost as if she kept riding it all these years, and somehow wound up in the Bay Area working a tech job she loathed. Her exchange that follows with [main character] Jimmie, however brief, has been written about and quoted more than any other part of the film.

Birch married talent manager Michael Benton Adler on December 21, 2018.
Birch is a long-time Democrat. She was a delegate at the 2012 Democratic National Convention. She has supported Joe Biden and local political efforts, such as Congressman Wiley Nickel's campaign.
Birch came out as bisexual in a 2026 interview with Us Weekly.
