The 2020–21 New Mexico State Aggies men's basketball team represented New Mexico State University during the 2020–21 NCAA Division I men's basketball season.

The Aggies were led by fourth-year head coach Chris Jans and were members of the Western Athletic Conference.

Due to COVID-19 restrictions in the state of New Mexico, the Aggies did not play their home games at their normal home arena, the Pan American Center.

Instead, they played their "home" games at various different locations, mainly in the Phoenix, Arizona area.

However, the NCAA Tournament was also cancelled due to the same outbreak.
