Juan Carlos Mortensen is an Ecuadorian professional poker player of Danish descent and the first South American Main Event winner of the World Series of Poker. Mortensen is known for his loose play, bluffing tactics, and interesting chip-stacking style.

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.
