Uncle Meat is the sixth album by the Mothers of Invention, and seventh overall by Frank Zappa, released as a double album in 1969. Uncle Meat was originally developed as a part of No Commercial Potential, a project which spawned three other albums sharing a conceptual connection: We're Only in It for the Money, Lumpy Gravy and Cruising with Ruben & the Jets.

The album also served as a soundtrack album to a proposed science fiction film which would not be completed, though a direct-to-video film containing test footage from the project was released by Zappa in 1987. The music is diverse in style, drawing from orchestral, jazz, blues and rock music. Uncle Meat was a commercial success upon release, and has been highly acclaimed for its innovative recording and editing techniques, including experiments in manipulation of tape speed and overdubbing, and its diverse sound.
