The 2014–15 Illinois State Redbirds men's basketball team represented Illinois State University during the 2014–15 NCAA Division I men's basketball season.

The Redbirds, led by third-year head coach Dan Muller, played their home games at Redbird Arena in Normal, Illinois as a member of the Missouri Valley Conference.

As the number four seed in the MVC tournament, they defeated Evansville in a quarterfinal game and eighth ranked Wichita State in a semifinal game before succumbing to eleventh ranked Northern Iowa in the final.

They received an at-large bid to the National Invitation Tournament where they won over Green Bay in the first round before losing to Old Dominion in the second round.

On April 7, following the conclusion of the NCAA tournament title game, deputy director of athletics Aaron Leetch and men's basketball associate head coach Torrey Ward were among seven people who perished during an airplane crash of a twin-engine Cessna 414 in a soybean field on the eastern outskirts of Bloomington, Illinois.
