The 1947 NAIA National Tournament was held in March at Municipal Auditorium in Kansas City, Missouri. The 10th annual men's basketball tournament of what is now the National Association of Intercollegiate Athletics (NAIA) featured 32 teams playing in a single-elimination format.[1]
It would be the first time since 1945 the NAIA Semifinalist would feature four new teams. Becoming the 3rd tournament to do so, and a feat that would not be repeated until 1965.
The championship game featured Marshall defeating Mankato State, 73–59. The third place game featured Arizona State-Flagstaff, now Northern Arizona, defeating Emporia State, 47–38.
1947 kicked off the "golden age" of NAIA National Tournaments. Harold Haskins became the first of 16 all-time leading scorers.Coach John Wooden withdrew Indiana State from the tournament because the NAIB would not allow black student-athlete Clarence Walker to play.[2] The NAIB changed in time for Walker to play for Indiana in the 1948 tournament.
Many of the records set by the 1947 tournament have been broken, and many of the awards were established much later:
