Cornelius is a fictional character in the Planet of the Apes universe. He first appears in Pierre Boulle's novel La Planète des singes, and goes on to appear in the first three films of the franchise: Planet of the Apes (1968), Beneath the Planet of the Apes (1970), and Escape from the Planet of the Apes (1971). He was portrayed by actor Roddy McDowall in the first and third films; owing to McDowall's absence, he was played instead by David Watson in Beneath.
