The 2015–16 Western Michigan Broncos men's basketball team represented Western Michigan University (WMU) during the 2015–16 NCAA Division I men's basketball season. The Broncos, led by 13th year head coach Steve Hawkins, played their home games at University Arena as members of the West Division of the Mid-American Conference (MAC). They finished the season 13–19 overall and 7–11 in MAC play to finish in last place in the West Division. They lost in the first round of the MAC tournament to Northern Illinois. WMU tied Eastern Michigan for the Michigan MAC Trophy with a 3–1 record. However, due to not having a clear winner, Central Michigan retained the trophy that they won in 2014–15.
