The 1957 NCAA University Division Basketball Tournament involved 23 schools playing in single-elimination play to determine the national champion of men's college basketball in the NCAA University Division, known since 1973 as NCAA Division I. The 1956–57 school year was the first in which NCAA members were formally divided into separate competitive levels, with larger and more competitive athletic programs placed in the University Division and smaller programs placed in the College Division (which would itself be divided into Divisions II and III in 1973). The tournament began on March 11, 1957, and ended with the championship game on March 23 in Kansas City, Missouri. A total of 27 games were played, including a third place game in each region and a national third place game.
North Carolina won two consecutive triple overtime games to win the championship. The North Carolina - Michigan State semi final game and North Carolina - Kansas final game both made USA Today's list of the greatest NCAA tournament games of all time at 11 and 6 respectively.
