Peter John Sallis, OBE (1 February 1921 – 2 June 2017) was an English actor, known for his work on British television. He was the voice of Wallace in the Academy Award-honoured Wallace and Gromit films and played Norman "Cleggy" Clegg in Last of the Summer Wine from its 1973 inception until its final episode in 2010, making him the only actor to appear in all 295 episodes.

Although Sallis was born and brought up in London, his two best remembered roles required him to adopt the accent and mannerisms of a Northerner. He also voiced Rat in The Wind in the Willows, appeared in Danger Man in the episode "Find and Destroy" (1961) as Gordon, appeared in the BBC Doctor Who serial "The Ice Warriors" (1967), playing renegade scientist Elric Penley, and appeared in an episode of The Persuaders! ("The Long Goodbye", 1971). Other appearances include The Curse of the Werewolf (1961), and Taste the Blood of Dracula (1970). He retired from acting in 2010 and died in 2017, aged 96.
