Moog is a 2004 American documentary film by Hans Fjellestad about electronic instrument pioneer Robert Moog. The film features scenes of Moog interacting with various musicians who view him as an influential figure in the history of electronic music.

Moog is not a comprehensive history of electronic music nor does it serve as a chronological history of the development of the Moog synthesizer. There is no narration, and the scenes feature candid conversation and interviews that serve more as a tribute to Moog than as a biographical documentary.

The film was shot on location in Hollywood, New York, Tokyo and Asheville, North Carolina, where Moog's company is based. Additional concert performances were filmed in London and San Francisco.

The film's 2004 release was designed to coincide with the fiftieth anniversary of Moog Music, Moog's company, founded as R. A. Moog Co. in 1954.
