"Episode 4", also known as "The One-Armed Man", is the fifth episode of the first season of the American surrealist mystery-horror drama television series Twin Peaks. The episode was written by Robert Engels and directed by Tim Hunter. "Episode 4" features series regulars Kyle MacLachlan, Piper Laurie and Richard Beymer, and introduces series co-creator David Lynch in the role of Gordon Cole.

Hunter's directing of the episode was inspired by Otto Preminger's 1945 film Fallen Angel, making use of small sets and long depth of field shots. Engels has identified several 1960s television series—The Wild Wild West, Mayberry R.F.D. and The Fugitive—as being influential to the series as a whole.

First airing on May 3, 1990, "Episode 4" was viewed by approximately 19 percent of the available audience during its broadcast, marking an increase in viewers from the previous week. "Episode 4" has received positive reviews from critics.
