The 2015–16 George Washington Colonials men's basketball team represented George Washington University during the 2015–16 NCAA Division I men's basketball season. The Colonials, led by fifth year head coach Mike Lonergan, played their home games at the Charles E. Smith Center and were members of the Atlantic 10 Conference. They finished the season 28–10, 11–7 in A-10 play to finish in fifth place. They defeated Saint Louis in the second round of the A-10 tournament to advance to the quarterfinals where they lost to Saint Joseph's. They received an invitation to the National Invitation Tournament. As a #4 seed, they defeated Hofstra, Monmouth, and Florida to advance to the semifinals at Madison Square Garden. At MSG, they defeated San Diego State and Valparaiso to become the 2016 NIT champions.
