The 2014–15 Big 12 men's basketball season began with practices in October 2014, followed by the start of the regular-season on November 14. Conference play is scheduled to begin on January 6, 2015, and conclude with the 2015 Big 12 men's basketball tournament, beginning March 11, 2015 at the Sprint Center in Kansas City.

The 2014–15 Kansas Jayhawks men's basketball team represented the University of Kansas in the 2014–15 NCAA Division I men's basketball season, which was the Jayhawks' 117th basketball season. The Jayhawks played their home games at Allen Fieldhouse. They were led by 12th year head coach Bill Self and were members of the Big 12 Conference. Despite losing 8 players, 5 who received substantial playing time, from the previous season, the Jayhawks still entered the season ranked 5th in the AP and Coaches poll, due in large part to a recruiting class ranked in the top 10 by Scout (4th), Rivals (3rd), and ESPN (9th). They finished the season 27–9, 13–5 in Big 12 play to finish win their 11th consecutive Big 12 regular season championship. They advanced to the championship game of the Big 12 tournament where they lost to Iowa State. They received an at-large bid to the NCAA tournament where they defeated New Mexico State in the second round before losing in the third round to cross state opponent, Wichita State. The Jayhawks 40–72 loss to Kentucky is the fewest points scored by Kansas in a game since the introduction of the shot clock in the 1985–86 season.
