Kenyon Lee Martin (born December 30, 1977) is an American professional basketball player. Nicknamed "K-Mart", he plays power forward for the Denver Nuggets of the NBA. He was selected first overall in the 2000 NBA Draft.

Martin played for the Cincinnati Bearcats under the direction of Bob Huggins. As a senior, he averaged 18.9 points, 9.7 rebounds and 3.5 blocks per game. He was the consensus National Player of the Year, earning numerous awards from various organizations, but suffered a broken leg in the Conference USA Tournament, keeping him out of the NCAA Tournament that year. Cincinnati retired his #4 jersey on April 25, 2000. Later that year, he was selected first overall in the 2000 NBA Draft by the New Jersey Nets. Martin is currently the last American-born college senior to have been the top overall pick; the top picks since him consist of three high school players (Kwame Brown, LeBron James and Dwight Howard), one international player with two years of U.S. college experience (Andrew Bogut), two international players with no American college experience (Yao Ming and Andrea Bargnani), three college freshmen (John Wall, Greg Oden and Derrick Rose) and a college sophomore (Blake Griffin).

Kenyon graduated with a Bachelor's Degree in Criminal Justice.
