List of Grand Slam men's doubles champions

Men's doubles championships at tennis's Grand Slam tournaments were first contested at the 1881 U.S. National Championships. Ken McGregor and Frank Sedgman are the only doubles players and team to achieve a calendar year Grand Slam, doing so in 1951, (the Bryans won four consecutive majors, but over the course of two calendar years), and their seven consecutive major titles remain the longest title streak in men's doubles major history.
