John Alexander Kneubuhl (July 2, 1920 – February 20, 1992) was an American Samoan screenwriter, playwright and Polynesian historian. He wrote for American television series such as The Fugitive, Gunsmoke, The Wild Wild West, Star Trek, The Invaders and Hawaii Five-O. The son of a Samoan mother and an American father, Kneubuhl's multicultural heritage produced a distinctive artistic vision that formed the basis of his most powerful dramatic work.
