Konstantinos (Kostas) Gousgounis (Greek: Κωνσταντίνος (Κώστας) Γκουσγκούνης, Larissa, 21 March 1931 – Elefsina, 6 May 2022) was a Greek comedian and photographer, known mainly for the erotic and pornographic films in which he starred between 1965 and 1984. He is referred to in the media as "legendary", "king of sex", "cult", "sex symbol".

He learned the art of photography in Larissa from his father Mimis Gousgounis and then went to Athens, where he later opened a photography studio in Cholargos. There he became known not only for his participation in erotic films, but also for his lines in them. His characteristic feature was that he always had his head shaved.
