Amélie Simone Mauresmo is a French professional tennis player. She is a former World No. 1. Mauresmo won two Grand Slam singles titles in 2006, at the Australian Open and at Wimbledon.

Mauresmo first attained the top ranking on September 13, 2004, holding it for five weeks on that occasion. She was the fourteenth World No. 1 in women's tennis since the computer rankings began. She is well known for her powerful one-handed backhand and her strong net play. She is coached by Loïc Courteau.

Although Mauresmo has been one of the top singles players for several years, she did not have success in winning Grand Slam tournaments until 2006. Her talents were never questioned, but Mauresmo was criticized for her mental strength after succumbing to nerves in those events. In consecutive Wimbledon championships, she lost to Serena Williams and Lindsay Davenportafter leading comfortably. Before her 2006 Australian Open title, Mauresmo was often touted as "the greatest women's player never to win a Grand Slam." After winning the 2006 Wimbledon title, Mauresmo openly joked, "I don’t want anyone to talk about my nerves any more."

Mauresmo is one of the few tennis players, male or female, to have reached the top ranking without first winning a Grand Slam singles title. Other players who had done so were Belgian Kim Clijsters, who ascended to the top spot in 2003, two years before winning her first Grand Slam singles title at the 2005 U.S. Open; Ivan Lendl, who first reached World No. 1 in 1983, before winning any of his eight Grand Slam singles titles; and Marcelo Ríos of Chile, who reached World No. 1 in 1998 but never won a Grand Slam singles title.
