The Gorn are a fictional extraterrestrial humanoid reptilian species in the American science fiction franchise Star Trek. They first appeared in a 1967 episode of the original series, "Arena", in which Captain Kirk fights an unnamed Gorn on a rocky planet. The fight scene has become one of the best-remembered scenes of the original series, in part due to the slow and lumbering movement of the Gorn, which some viewers have considered unintentionally comical.

Star Trek is an American science fiction television series created by Gene Roddenberry that follows the adventures of the starship USS Enterprise (NCC-1701) and its crew. It acquired the retronym of Star Trek: The Original Series (TOS) to distinguish the show within the media franchise that it began.
