American actor best known for playing the role of Fox (“Spooky”) Mulder on the television series The X-Files (1993–2002).

Duchovny was educated at Princeton University, where he received a B.A. degree, and at Yale University, where he earned an M.A. in English literature and began working on a Ph.D. He added acting classes in New York City to his schedule and began getting work, including a TV commercial for beer and some Off-Broadway plays. He left Yale in 1987 to live in New York City and later that year moved to Hollywood, where his first movie roles were in Working Girl (1988) and the independent film New Year's Day (1989). Other credits followed, notably Julia Has Two Lovers (1991), The Rapture (1991), Chaplin (1992), and Kalifornia (1993). In the early 1990s he began working in television, taking such roles as Jake on The Red Shoe Diaries and the memorable transvestite detective Dennis/Denise on Twin Peaks.

In 1993 Duchovny was cast as FBI Special Agent Mulder, a believer in space aliens and government conspiracies, on Fox's The X-Files. His partner in paranormal crime-solving was a scientist named Dana Scully (played by Gillian Anderson (Anderson, Gillian)). The show was popular among viewers who liked the chemistry between Duchovny and Anderson as well as the show's inventive plots. The series spawned two motion pictures—The X-Files: Fight the Future (1998) and The X-Files: I Want to Believe (2008).

Duchovny also starred in the films Playing God (1997), Return to Me (2000), and Full Frontal (2002). In 2004 he directed his first motion picture, The House of D, a dramedy that he also wrote. His later television work included the series Californication (2007– ), in which he starred as a self-destructive writer.
