William Charles Renshaw (3 January 1861 – 12 August 1904) was a British tennis player active during the late 19th century, who was ranked world No.

[5] Since 1922 the reigning champions have had to play in the main draw, making such feats considerably more difficult.

He was unable to defend his title in 1887 because of tennis elbow, the first time this injury received public attention, and during his absence took up golf.

Additionally, he and his brother dominated the sport for many years in a time when the only other Grand Slam was the U.S. Championships, and by custom players did not travel far.

[6] In 1983, William Renshaw was elected posthumously into the International Tennis Hall of Fame together with his brother.
