2010 National Invitation Tournament

The 2010 National Invitation Tournament was a single-elimination tournament of 32 National Collegiate Athletic Association (NCAA) Division I teams that were not selected to participate in the 2010 NCAA Division I men's basketball tournament. The 73rd annual tournament began on March 16 on campus sites and ended on April 1 at Madison Square Garden in New York City. Dayton won their 3rd NIT title (first title since 1968) over North Carolina, 79–68.

Automatic qualifiers
The following teams were automatic qualifiers for the 2010 NIT field after losing in their respective conference tournaments, by virtue of winning their conferences' regular season championship and not qualifying for the NCAA tournament.

* Jacksonville split the Atlantic Sun regular season title with Campbell, Lipscomb and Belmont, but the conference tournament was won by fifth-seeded East Tennessee State. The Dolphins earned the automatic NIT bid by advancing the furthest of the four in the Atlantic Sun tournament even though Lipscomb was the #1 seed in the tournament.

The entire 32-team field was announced on March 14, 2010, on The NIT Selection Show at 9 pm ET on ESPNU.
