The 2015–16 UMass Lowell River Hawks men's basketball team represented the University of Massachusetts Lowell during the 2015–16 NCAA Division I men's basketball season.

They were coached by third year head coach Pat Duquette and played most of their home games at Costello Athletic Center, with five home games at the Tsongas Center.

They were a member of the America East Conference.

UMass Lowell was in the third year of a transition to Division I and thus ineligible for the postseason, including the America East tournament.

The River Hawks finished the season 12–17, 6–10 in America East play to finish in sixth place.
