John Yocum Randolph Crawford (August 4, 1915 – February 14, 1976) was an American bridge and backgammon player.
In bridge, he was a member of United States teams that won the first three Bermuda Bowls, or world teams championships, in 1950, 1951 and 1953; a wholly new team represented the US in 1954.
In backgammon, Crawford is known as the inventor of the "Crawford rule", a regulation that restricts use of the doubling cube in match play.
