The 2015–16 TCU Horned Frogs men's basketball team represented Texas Christian University in the 2015–16 NCAA Division I men's basketball season, led by head coach Trent Johnson in his fourth and final season at TCU.

The Horned Frogs were members of the Big 12 Conference and played their home games at Schollmaier Arena, which reopened in December after a $72 million upgrade.

Some early season, non-conference games were played in the TCU University Recreation Center and the Wilkerson-Greines Activity Center while construction on Schollmaier Arena was completed.

They defeated Texas Tech in the first round of the Big 12 tournament to advance to the quarterfinals where they lost to West Virginia.

In 2014–15, the Horned Frogs started the season 14–0, climbing to #25 in national polls.
