John Carson  was a British actor noted for his appearances in film and television.

Making his film debut in 1947, he carved out a career appearing in low budget British movies such as Seven Keys (1961); Smokescreen (1964); and Master Spy (1964). His saturnine looks and sinister voice (not unlike James Mason) led to him starring in a number of horror films including The Night Caller (1965); Plague of the Zombies (1965); The Man Who Haunted Himself (1970); Taste the Blood of Dracula (1970); and Captain Kronos - Vampire Hunter (1972).

Beside his appearances in horror films he is also known for his many villainous turns in adventure series of the sixties, such as The Avengers; The Saint; Adam Adamant Lives!; The Baron; Man in a Suitcase; The Champions; and Department S.

His long and varied list of television credits include The Adventures of Robin Hood; Emergency - Ward 10; Ivanhoe; William Tell; Armchair Theatre; Maigret; Out of the Unknown; Emma (as Mr. Knightley); Dixon of Dock Green; Crown Court; The New Avengers; Secret Army; The Professionals; Tales of the Unexpected; Hammer House of Horror; and Poirot. He was also famously the voice-over on the Sunsilk TV commercial that featured the John Barry music "The girl with the sun in her hair".

In 1983 he appeared as Ambril in the fifth Doctor story Snakedance.

He died peacefully in Cape Town, South Africa in 2016.
