Baa Baa Black Sheep (renamed Black Sheep Squadron for the second season) is an American television series that aired on NBC from September 23, 1976, until April 6, 1978. It was part period military drama, part comedy. In the final seven episodes, the character list was revamped, dropping some squadron pilots, adding a 16-year-old pilot and four nurses.

Its original premise was based on the experiences of United States Marine Corps aviator Greg Boyington and his World War II "Black Sheep Squadron". The series was created and produced by Stephen J. Cannell. The opening credits read: "In World War II, Marine Corps Major Greg 'Pappy' Boyington commanded a squadron of fighter pilots. They were a collection of misfits and screwballs who became the terrors of the South Pacific. They were known as the Black Sheep."
