Michael Creighton Balfour (11 February 1918 – 24 October 1997) was an English actor, working mainly in British films and TV, following his TV debut in the BBC's The Marvellous History of St Bernard, in 1938. He was a recognisable face, often in small character parts and supporting roles, in nearly two hundred films and TV shows, from the 1940s to the 1990s, often playing comical heavies or otherwise shady characters notable for their "loud" clothes, sometimes convincingly cast as an American.

He worked for a roll call of film directors, including Tony Richardson, Pete Walker, Billy Wilder, Lewis Gilbert, Roman Polanski, Leslie Norman, Tim Burton, John Frankenheimer, François Truffaut, John Gilling, Stanley Donen, Ken Annakin, Cavalcanti, Lance Comfort, Terence Young, Gerald Thomas, Pasolini, John Paddy Carstairs, Terence Fisher, Val Guest, Frank Launder, John Huston, Basil Dearden and Howard Hawks.
