The 2015–16 William & Mary Tribe men's basketball team represented the College of William & Mary during the 2015–16 NCAA Division I men's basketball season. The Tribe were led by thirteenth year head coach Tony Shaver. The team played its home games at Kaplan Arena and remained members of the Colonial Athletic Association (CAA). This was the 111th season of the collegiate basketball program at William & Mary. They finished the season 20–11, 11–7 in CAA play to finish in a three way tie for third place. They advanced to the semifinals of the CAA tournament where they lost Hofstra. Despite again securing twenty wins for the season, the Tribe failed to secure back-to-back postseason tournament bids for the first time in program history. Along with the 2013–14 and 2014–15 seasons, this was only the second time in program history that William & Mary won twenty games during three consecutive seasons.
