A Boy Named Charlie Brown is a 1969 American animated musical comedy-drama film, produced by Cinema Center Films, distributed by National General Pictures, and directed by Bill Melendez with a screenplay by Charles M. Schulz. It is the first feature film based on the Peanuts comic strip. Starring Peter Robbins, Pamelyn Ferdin, Glenn Gilger, and Andy Pforsich, the film follows the titular character as he tries to win the National Spelling Bee, with Snoopy and Linus by his side. The film was produced by Lee Mendelson.

The film was based on a comic strip storyline from February 1966, which ended differently when Charlie Brown lost his local school's spelling bee. Regular Peanuts composer Vince Guaraldi and John Scott Trotter composed the score while Rod McKuen wrote many of the songs as well as the title song "A Boy Named Charlie Brown". This film was the last time Peter Robbins provided the voice of Charlie Brown.

Releasing on December 4, 1969, A Boy Named Charlie Brown was a box-office success, grossing $12 million and was positively received by critics. The franchise would go on to produce four more Peanuts films, with Snoopy Come Home following in 1972.
