Orlando is a British television thriller series for young adults which ran for four series between 1965 and 1968. Made by Associated-Rediffusion for the ITV network, it stars Sam Kydd as Orlando O'Connor, the character he had played in the adult television series Crane.

Only four episodes out of the 76 made are known to still exist; the remainder are lost. It introduced an evocative theme tune "The Hellraisers" by Syd Dale, which became a commonplace adventure underscore cue as library music for other productions worldwide.
