Todd Martin (born July 8, 1970) is an American retired tennis player. He reached the men's singles final at the 1994 Australian Open and the 1999 US Open and achieved a career-high singles ranking of world No. 4.

Playing career Martin was born in Hinsdale, Illinois, and played tennis for two years at Northwestern University before turning professional in 1990. His parents lived in Lansing, Michigan, where Martin went to nearby East Lansing High School. At Northwestern, he was a member of the Delta Tau Delta fraternity. He won his first top-level singles title in 1993 at Coral Springs, Florida. Martin traveled with good friend David Helfer for much of the '92 season. Helfer went on to play at Kalamazoo College.

1994 proved to be a breakout year for Martin. Coached by Robert Van't Hof, at the year's first Grand Slam tournament, he reached the men's singles final at the Australian Open, where he lost in straight sets to No. 1 Pete Sampras. At Wimbledon, he made it to the semifinals, before falling to the eventual champion Sampras; the set that Martin took from Sampras in the match was the only set that Sampras lost during the entire tournament. Martin's third Grand Slam semifinal of 1994 came at the US Open, where he again fell to the eventual champion, this time Andre Agassi. He also captured singles titles at Queen's Club and the Regions Morgan Keegan Championships in Memphis, the latter of which was the first back-to-back titles.

Martin was a member of the US team Davis Cup for nine consecutive years and part of the championship squad in 1995 (beating Russia 3–2 in the final). He also reached the final of the 1995 Grand Slam Cup, where he lost in straight sets to Goran Ivanišević. He reached the Wimbledon semifinals again in 1996, but eventually lost 10-8 in the fifth set against MaliVai Washington, after holding a 5–1 lead in the final set and serving for the match twice. Martin would later reflect on the outcome and admit that he choked during the crucial moments of the match. He missed most of the 1997 season due to injury, but came back to win two singles titles in Barcelona and Stockholm in 1998.

In 1999, Martin had a solid year, reaching the quarterfinals of both the Australian Open and Wimbledon, and reached his second Grand Slam final at the US Open. Along the way, Martin had a memorable battle with Greg Rusedski in the fourth round, in which Rusedski held numerous advantages, including a two sets to love lead, serving for the match in the third set, and a 4–1 advantage in the fifth. Yet, Martin was able to prevail in five sets. Martin won 20 of the final 21 points of the match, despite playing with a heavily bandaged leg and dealing with dehydration. In the final, he faced Andre Agassi in a five-set contest, which Agassi eventually won. Martin won another singles title in Sydney that year, and reached his career-high singles ranking of No. 4.

In 2000, Martin again turned in a strong performance at the US Open, reaching the semifinals before falling to the eventual champion, Marat Safin, in straight sets. As with the previous year's tournament, Martin made another grueling comeback from a two-set deficit in the fourth round, this time against Carlos Moyà.

Martin was named the ATP's Most Improved Player in 1993, and won its Sportsmanship Award in 1993 and 1994. He was president of ATP Players Council for 1995–97 and 1998–99.

From 1994 to 1996, Martin was coached by Robert Van't Hof; from 1997 to 2002, he was coached by Dean Goldfine.

In his career, Martin won eight singles and five doubles titles. He retired from the professional tour in 2004. He was the CEO of the International Tennis Hall of Fame until the end of 2022. He is currently the Tournament Director for the Western & Southern Open and is also the Head of Tennis for Beemok Sports and Entertainment.
