Leonard Part 6 is a 1987 comedy film that parodies spy movies. It was directed by Paul Weiland and starred Bill Cosby, who also produced the film and wrote its story. The movie also starred Joe Don Baker and Gloria Foster, the latter of whom played the villain. The movie was filmed in the San Francisco Bay Area, and was rated PG by the Motion Picture Association of America. It earned several Golden Raspberry Awards; Cosby himself denounced and disowned it in the press in the weeks leading up to its release.

Bill Cosby plays Leonard Parker, a former CIA spy. According to the opening sequence of the movie, the title refers to the idea that this film is actually the sixth installment of a series of films featuring the adventures of Leonard, as parts one through five were locked up in the interests of world security.

The movie starts with Parker being re-recruited by his former employers in the CIA to save the world from an evil vegetarian who brainwashes animals to kill people. The film ends with Leonard infiltrating the vegetarian base, fending off the vegetarians with magic meat he received from a Gypsy, freeing the captive animals and flooding the base using Alka-Seltzer. He escapes by riding an ostrich on the roof of the building, with the ostrich flying him down.
