The 2015–16 BYU Cougars men's basketball team represents Brigham Young University in the 2015–16 NCAA Division I men's basketball season. It is head coach Dave Rose's eleventh season at BYU and the Cougars fifth season in the West Coast Conference. The Cougars once again play their home games at the Marriott Center. As a result of a scandal surrounding inappropriate benefits received by BYU starting guard Nick Emery from a BYU booster, the NCAA vacated all of BYU's wins for the 2015–16 and 2016–17 seasons with the exception of a 2015 win over Weber State in which Nick Emery did not play.
