Francis "Frank" Arthur Sedgman (born 29 October 1927) is an Australian former world No. 1 tennis player. Over the course of a three-decade career, Sedgman won five Grand Slam singles tournaments as an amateur as well as 22 Grand Slam doubles tournaments. He is one of only five tennis players all-time to win multiple career Grand Slams in two disciplines, alongside Margaret Court, Roy Emerson, Martina Navratilova and Serena Williams. In 1951, he and Ken McGregor won the Grand Slam in men's doubles. Sedgman turned professional in 1953, and won the Wembley World Professional Indoor singles title in 1953 and 1958. He also won the Sydney Masters tournament in 1958, and the Melbourne Professional singles title in 1959. He won the Grand Prix de Europe Professional Tour in 1959. Sedgman was ranked as the world No. 1 amateur in 1950 by Harry Hopman and Ned Potter, in 1951 by Pierre Gillou, Hopman and Potter and in 1952 by Lance Tingay, Gillou, Hopman and Potter. Tennis de France magazine ranked Sedgman as the world No. 1 professional tennis player for the 1953 season. Jack Kramer, in his personal ranking lists, ranked Sedgman as the world No. 2 professional behind Pancho Gonzales for the 1958, 1959 and 1960 seasons.

He was particularly known for his volleying and speed at the net. When asked in 2005 who was the best player he had ever faced, Mervyn Rose replied, "Hopman's pet, Sedgie." Sedgman led the Australian Davis Cup team to victory in 1950, 1951, and 1952. In a five-year span from 1948 through 1952 Sedgman won 22 Grand Slam titles in singles, doubles, and mixed doubles. Sedgman and his partner Ken McGregor were the only men's doubles team to ever win the Grand Slam in a single year—they won all four majors in 1951. The following year they also won the first three majors, then, at Forest Hills, were upset by a pick-up team of another Australian, Mervyn Rose, and an American Vic Seixas, denying them eight consecutive Grand Slam victories.
