Cyril Ring (December 5, 1892 – July 17, 1967) was an American film actor. He began his career in silent films in 1921. By the time of his final performance in 1951, he had appeared in over 350 films, nearly all of them in small and/or uncredited bit parts.

Ring is probably best known today for his role as Harvey Yates, a con artist and accomplice to fellow con artist Penelope, played by Kay Francis in the Marx Brothers first film The Cocoanuts (1929). He also appeared in uncredited small parts in two other Marx films, Monkey Business (1931) and A Day at the Races (1937).
