Ronald Edward Galella (born January 10, 1931) is an American photographer, known as a pioneer paparazzo. Dubbed "Paparazzo Extraordinaire" by Newsweek and "the Godfather of the U.S. paparazzi culture" by Time magazine and Vanity Fair, he is regarded by Harper's Bazaar as "arguably the most controversial paparazzo of all time".

He immortalized many celebrities out of the public eye and gained notice for his feuds with some of them, including Jacqueline Onassis and Marlon Brando. Despite the numerous controversies and claims of stalking, Galella's work has been praised and exhibited in art galleries worldwide and he was cited by Andy Warhol as his favorite photographer.

During his career, Galella has taken more than three million photographs of public figures.
