Tom Izzo is a renowned college basketball coach. In 1995, Izzo was named head coach of the Michigan State University men's basketball team.

Izzo has led the Spartans to the 2000 NCAA Division I National Championship, the 2009 NCAA National Championship Game, eight Final Fours, ten Big Ten championships, and six Big Ten Tournament championships in his 25 years at Michigan State. The coach with the most wins in school history, Izzo's teams have earned invitations to 22 consecutive NCAA tournaments, and his teams have never had a losing season (records as of 2021). In addition, MSU set a Big Ten record for the longest home court winning streak. These accomplishments led analyst Andy Katz at ESPN to deem Michigan State the top college basketball program from 1998 to 2007. Also as of 2021, Izzo is currently the longest-tenured coach in the Big Ten Conference, and his teams are often recognized for their rebounding prowess and defensive tenacity. He has won four national coach of the year awards and maintains a considerable coaching tree—several of his former assistants are currently head coaches at other Division I schools.

Izzo has won ten regular-season conference titles, the third most in conference history. He has also won the most Big Ten Tournament titles (six) in conference history. Izzo is second all-time in Big Ten wins (302 through 2020), trailing only Bob Knight. In April 2016, Izzo was elected to the Naismith Basketball Hall of Fame.
