Detective Chief Inspector Endeavour Morse, GM, is the eponymous fictional character in the series of detective novels by British author Colin Dexter. On television, he appears in the 33-episode drama series Inspector Morse (1987–2000), in which John Thaw played the character, as well as the (2012–2023) prequel series Endeavour, portrayed by Shaun Evans.

In his later career he is usually assisted by Sergeant
