The 1989–90 Michigan State Spartans men's basketball team represented Michigan State University in the 1989–90 NCAA Division I men's basketball season. The team played their home games at newly-opened Breslin Center in East Lansing, Michigan and were members of the Big Ten Conference. They were coached by Jud Heathcote in his 14th year at Michigan State. The Spartans finished the season with a record of 28–6, 15–3 to win the Big Ten championship by two games. As the No. 3-ranked team in the country, they received the conference's automatic bid to the NCAA tournament as the No. 1 seed in the Southeast region. In the first round, they narrowly avoided becoming the first No. 1 seed to lose a No. 16 seed, beating Murray State in overtime. They then defeated UC Santa Barbara in the second round to earn a trip to the Sweet Sixteen, their first trip since 1986. There they lost in overtime to Georgia Tech.

Ken Redfield was named the Big Ten Defensive Player of the Year.
