Crandell Addington was an American businessman and poker player who is best known as one of the founders of the World Series of Poker, and is a member of the Poker Hall of Fame.

The World Series of Poker (WSOP) is a series of poker tournaments held annually in Paradise, Nevada and, since 2004, sponsored by Caesars Entertainment. It dates its origins to 1970, when Benny Binion invited seven of the best-known poker players to the Horseshoe Casino for a single tournament, with a set start and stop time, and a winner determined by a secret ballot of the seven players.
