Thomas Johansson is a professional tennis player. He joined the pro tour for the first time in 1993 and has won 9 top-level singles titles and 1 doubles title, including the 1999 Canada Masters and the 2002 Australian Open Grand Slam championship, which he unexpectedly won after defeating his heavily favored opponent, Marat Safin, in four sets, 3–6 6–4 6–4 7–6. Johansson became the first Swedish player to win a Slam since Stefan Edberg won the 1992 U.S. Open title, and the first Swede to claim the Australian since Mats Wilander in 1988.

Johansson would later reach his career high ranking of World No. 7 in June of 2002 and finish the season with a career best year-end ranking of 14th in the ATP Champions Race, a feat he would later repeat in 2005.
