Sweeney 2 is a 1978 British action crime drama film. It was made as a sequel to the successful 1977 film Sweeney!. Both films are an extension of the popular British ITV television series The Sweeney (1975–78). Some of the action in the film is transferred from the usual London setting to Malta.

The series and films depict a fictionalised version of the Flying Squad. The term The Sweeney is derived from Cockney rhyming slang, originating in the expression Sweeney Todd: Flying Squad, and is a real term used by the London underworld to refer to the Squad, whose brief was to investigate armed robbery within the Metropolitan Police District (MPD), an area roughly corresponding to Greater London.

The film centres on the investigations of the fictional Detective Inspector Jack Regan (John Thaw) and his partner Detective Sergeant George Carter (Dennis Waterman).
