The 1946 NCAA Men's Division I Basketball Tournament involved 8 schools playing in single-elimination play to determine the national champion of men's NCAADivision Icollege basketball. It began on March 21, 1946, and ended with the championship game on March 26 in New York City. A total of 10 games were played, including a third place game in each region and a national third place game.
This was the first tournament to have four teams advance to the final site, though not the first to have a true "Final Four" format (that would not occur until 1952). The two regional losers played in the national third-place game, while the two winners played for the championship. The third place game would continue through the 1981 tournament.
