Robert David "Bob" Hamman (born August 6, 1938 in Pasadena, California) is an American professional bridge player, among the greatest players of all time. He is from Dallas, Texas. Hamman and Bobby Wolff played as partners for nearly three decades on teams that challenged for major trophies in North America and often for world championships. Representing the United States (from about 1980, previously North America) they won eight world championships for national teams, the 1988 World Team Olympiad and seven Bermuda Bowls spanning 1970 to 1995. For the last they were members of Nick Nickell's professional team, where Hamman remained a fixture through the current two-year cycle and won three more Bermuda Bowls in partnership with Paul Soloway and Zia Mahmood.
