Sarah Wynter (born 15 February 1973) is an Australian actress, most widely known for her roles on American television – such as Kate Warner on the television drama 24, as Beth on Windfall, and as Keitha on Flight of the Conchords.

On 20 August 2005, Wynter married Details magazine editor-in-chief Dan Peres in Sydney. The couple have three children. The couple divorced in 2014.
Wynter's interest in acting led her to move to New York City when she was 17 to study drama.
Wynter earned her SAG card by landing a role on the Sex and the City pilot, playing what she later summarized as the first woman to have sex on that show.
A few years later, she was recognized by SAG again, as part of the second season cast of 24 when it earned a SAG Award nomination as Best Performance by an Ensemble in a Drama Series. Wynter played Kate Warner and appeared in all 24 episodes, plus the third season premiere and she provided her voice for 24: The Game.
