Julianne Moore (born Julie Anne Smith; December 3, 1960) is an American–British actress, prolific in cinema since the early 1990s. She is particularly known for her portrayals of emotionally troubled women, in both art house and Hollywood films, and has received many accolades including the Academy Award for Best Actress.

After studying theatre at Boston University, Moore began her career with a series of television roles. From 1985 to 1988, she was a regular in the soap opera As the World Turns, earning a Daytime Emmy for her performance. Her film debut was in Tales from the Darkside: The Movie (1990), and she continued to play small roles for the next four years – including in the thriller The Hand That Rocks the Cradle (1992). Moore first received critical attention with Robert Altman's Short Cuts (1993), and successive performances in Vanya on 42nd Street (1994) and Safe (1995) continued this acclaim. Starring roles in the blockbusters Nine Months (1995) and The Lost World: Jurassic Park (1997) established her as a leading actress in Hollywood, although she continued to take supporting roles.

Moore received considerable recognition in the late 1990s and early 2000s, earning Oscar nominations for Boogie Nights (1997), The End of the Affair (1999), Far from Heaven (2002) and The Hours (2002); in the first of these she played a 1970s pornography actress, while the other three featured her as an unhappy, mid-20th century housewife. She also had success with the films The Big Lebowski (1998), Magnolia (1999), Hannibal (2001), Children of Men (2006), A Single Man (2009) and The Kids Are All Right (2010), and won several awards for her portrayal of Sarah Palin in the television film Game Change (2012). The year 2014 was key for Moore, as she gave an Oscar-winning performance as an Alzheimer's patient in Still Alice, was named Best Actress at the Cannes Film Festival for Maps to the Stars, and appeared in the Hunger Games series.

In addition to acting, Moore has written a series of children's books about the character "Freckleface Strawberry". She is married to director Bart Freundlich, with whom she has two children.
