The 2019–20 Illinois Fighting Illini men's basketball team represented the University of Illinois at Urbana–Champaign in the 2019–20 NCAA Division I men's basketball season.

Led by third-year head coach Brad Underwood, the Illini played their home games at State Farm Center in Champaign, Illinois as members of the Big Ten Conference.

Their season ended following the cancellation of postseason tournaments due to the COVID-19 pandemic.

Cockburn and Feliz did not come on the trip due to visa issues.
