Kenneth Bruce McGregor (2 June 1929 – 1 December 2007) was a tennis player from Australia who won the Men's Singles title at the Australian Championships (now known as the Australian Open) in 1952. He and his longtime doubles partner, Frank Sedgman, are generally considered one of the greatest men's doubles teams of all time. In 1951 and 1952, they won seven consecutive Grand Slam doubles titles – a feat that has never been matched. McGregor was also a member of three Australian Davis Cup winning teams in 1950–1952. At the end of 1952, Jack Kramer induced both Sedgman and McGregor to turn professional. He was ranked as high as World No. 3 in 1952.
