FBI Special Agent Fox William Mulder () is a fictional character in the Fox science fiction-supernatural television series The X-Files, played by David Duchovny. Mulder's peers consider his (often correct) theories on extraterrestrial activity as spooky and far-fetched. With his FBI partner Dana Scully, he works in the X-Files office, which is concerned with cases with particularly mysterious or possibly paranormal circumstances that were left unsolved and shelved by the FBI. Mulder was a main character for the first seven seasons, but was limited to a recurring character for the following two seasons. He returns as a main character for the tenth and eleventh seasons.

Mulder made his first appearance in the first season pilot episode, broadcast in 1993. Mulder believes in extraterrestrial unidentified flying objects (UFOs) and a government conspiracy to hide or deny the truth of their existence. Mulder considers the X-Files and the truth behind the supposed conspiracy so important that he has made them the main focus of his life.
