Joseph Hachem is a Lebanese-Australian professional poker player known for being the first Australian to win the World Series of Poker main event, which earned him $7.5 million, then a record for all-time biggest tournament prize.

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.
