William "Bill" Walter Boyd (January 27, 1906 – November 21, 1997) was a professional poker player.

Boyd was a five-card stud player; he won all four of his World Series of Poker bracelets in five-card stud. Boyd and Doyle Brunson are the only players in the history of the WSOP to have won bracelets in four consecutive years.

Additionally, Boyd is responsible for the spread of Omaha hold 'em. In 1983 Robert "Chip Burner" Turner, the creator of the game, approached Boyd, who was then the director of operations at the Golden Nugget casino in Las Vegas, Nevada. The game, previously not having a name, was called Nugget hold 'em. Sometime later it was renamed to its current name of Omaha hold 'em.

Boyd managed the card room at the Golden Nugget from the day it opened in 1946 to its closing in 1982

As a tribute to his long career, he was dealt the first poker hand ever at The Mirage. He was elected to the Poker Hall of Fame in 1981.

Boyd died in Las Vegas on November 21, 1997 at the age of 91.
