The 1955 NAIA basketball tournament was held in March at Municipal Auditorium in Kansas City, Missouri. The 18th annual NAIA basketball tournament featured 32 teams playing in a single-elimination format.[1]
The 1955 tournament featured four of the all-time leading scorers, two single-game best tournament performances, and most free throws made in tournament history.
The championship game featured East Texas State (now Texas A&M-Commerce) and Southeastern Oklahoma State. East Texas State defeated SEOSU, 71–54. The other teams in the NAIA Semifinals were Western Illinois State and Arkansas Tech. The Leathernecks defeated the Wonder Boys for the third place title, 77–74.
