Texas hold 'em (also hold'em, holdem) is the most popular of the community card poker games. It is also the most popular poker variant played in most casinos in the United States. Its no-limit betting form is used in the main event of the World Series of Poker (WSOP) and the World Poker Tour.

Although it can theoretically be played by up to 22 players (or 23 if burn cards are not used), it is generally played with between 2 and 10 people. It is one of the most positional of all poker variants, since the order of betting is fixed throughout all betting rounds. Hold 'em is commonly played outside of the United States, but seven-card stud, Omaha hold 'em and other games may be more popular in some places.
