Big 12 Conference Men's Basketball Coach of the Year

The Big 12 Conference Men's Basketball Coach of the Year is a basketball award given to the most outstanding men's basketball head coach in the Big 12 Conference, as chosen by a panel of sports writers and broadcasters. The award was first given following the 1996–97 season, the first year of the conference's existence, to Kansas Jayhawks head coach Roy Williams.

As of 2020, current Kansas Jayhawks head coach Bill Self has won the award six times, leading the league. Four other head coaches, have won the award twice. The voting finished in a tie in 2011–12, with Self and Iowa State Cyclones head coach Fred Hoiberg sharing honors.

Three coaches have won Big 12 Conference Coach of the Year in the same season that they have also won a National Coach of the Year Award, Roy Williams, Larry Eustachy and Bill Self. The Kansas Jayhawks has the most Big 12 Conference Coach of the Year Awards with six while the Texas Longhorns are second with four. The only pre-2023 members that have never had a coach win are Oklahoma and TCU. Four other schools, namely BYU, Cincinnati, Houston, and UCF, are playing their first Big 12 seasons in 2023–24. Three former Big 12 members, Colorado (which will return in 2024), Missouri, and Nebraska, also never had a winner.
