The Lost Episodes is a 1996 posthumous album by Frank Zappa which compiles previously unreleased material. Much of the material covered dates from early in his career, and as early as 1958, into the mid-1970s. Zappa had been working on these tracks in the years before his death in 1993.

Frank Vincent Zappa was an American musician, composer, and bandleader. In a career spanning more than 30 years, Zappa composed rock, pop, jazz, jazz fusion, orchestral and musique concrète works; he also produced almost all of the 60-plus albums that he released with his band the Mothers of Invention and as a solo artist. His work is characterized by nonconformity, improvisation sound experimentation, musical virtuosity and satire of American culture. Zappa also directed feature-length films and music videos, and designed album covers. He is considered one of the most innovative and stylistically diverse musicians of his generation.
