Matthew Mayer

Matthew Mayer (born September 23, 1999) is an American professional basketball player for the Houston Rockets' Summer League team of the National Basketball Association (NBA). He played college basketball for the Illinois Fighting Illini and the Baylor Bears.

Mayer attended Westlake High School in Austin, Texas, where he played alongside future NCAA Division I players Brock Cunningham, Keonte Kennedy and Will Baker. He committed to playing college basketball for Baylor over offers from Texas and Texas A&M, among others. Mayer was a consensus four-star recruit, according to major recruiting services.

Mayer had a limited role during his first two years at Baylor. In his junior season, he improved his efficiency and was a key contributor off the bench for the national champion Bears. Mayer grew a mullet upon the advice of his teammate Jackson Moffatt, who had the same hairstyle. Mayer averaged 8.1 points and 3.7 rebounds per game. Following the season, he declared for the 2021 NBA draft, but ultimately returned for his senior season. In his senior season, Mayer started all 33 games and averaged 9.8 points and 5.0 rebounds per game. He again declared for the NBA draft after the season, but later withdrew and announced he was transferring to Illinois. In his lone season at Illinois, Mayer was named to the Third Team All-Big Ten by both coaches and media.

Mayer went undrafted in the 2023 NBA draft. He was then signed to play on the Houston Rockets' Summer League team. Mayer first appeared in the Rockets' third game of the Summer League.
