Captain Pugwash is a fictional pirate in a series of British children's comic strips and books created by John Ryan. The character's adventures were adapted into a TV series, using cardboard cut-outs filmed in live-action (the first series was performed and broadcast live), also called Captain Pugwash, first shown on the BBC in 1957, a later colour series, first shown in 1974–75, and a traditional animation series, The Adventures of Captain Pugwash, first aired in 1998.

The eponymous hero – Captain Horatio Pugwash – sails the high seas in his ship called the Black Pig, ably assisted by cabin boy Tom, pirates Willy and Barnabas, and Master Mate. His mortal enemy is Cut-Throat Jake, captain of the Flying Dustman.

Captain Horatio Pugwash made his debut in a comic-strip format in the first issue of The Eagle in 1950, then appeared regularly as a strip in Radio Times. In 1957 the BBC commissioned a series of short cartoon films produced by Gordon Murray. Ryan produced a total of 86 five-minute-long episodes for the BBC, shot in black-and-white film, but later transferring to colour. Ryan used a real-time technique of animation in which cardboard cutouts of the characters were laid on painted backgrounds and moved with levers. The characters' voices were provided by Peter Hawkins. The last series of Pugwash shorts by Ryan was produced in 1975.
