John Carradine (February 5, 1906 - November 27, 1988) was an American actor.

Born Richmond Reed Carradine in New York City, he began his career in show business as a Shakespearean dramatic actor and made his cinematic debut in 1930 under the name Peter Richmond. He adopted the stage name "John Carradine" in 1933, and took the name as his own two years later.

He appeared in more than 200 movies, mostly in the B-movie/Suspense genre. He also appeared in ten John Ford productions (including The Grapes of Wrath (1940)), portrayed Biblical hero Aaron in The Ten Commandments (1956), and made numerous television cameos. For his contribution to the motion picture industry, John Carradine has a star on the Hollywood Walk of Fame at 6240 Hollywood Blvd. In 2003, he was inducted into the Western Performers Hall of Fame at the National Cowboy & Western Heritage Museum in Oklahoma City, Oklahoma.

Carradine's idiosyncratic habit of strolling Hollywood streets while reciting Shakespearean soliloquies earned him the nickname "Bard of the Boardwalk".

Four sons, David, Robert, Keith and Bruce are also actors. John Carradine appeared with his son David in the pilot episode of Kung Fu.

He died in Milan, Italy, at the age of 82.
