The National Invitation Tournament (NIT) is an annual men's college basketball tournament operated by the National Collegiate Athletic Association (NCAA). The tournament is played at regional sites with its Final Four played at Madison Square Garden (MSG) in New York City up until 2022. Starting in 2023, the NIT Final Four began following the format of the NCAA Tournament by having its Final Four at different venues each season. First held in 1938, the NIT was once considered the most prestigious post-season showcase for college basketball before its status was superseded in the mid-1950s by the NCAA Division I men's basketball tournament.

In United States colleges and universities, basketball is governed by collegiate athletic bodies including the National Collegiate Athletic Association (NCAA), the National Association of Intercollegiate Athletics (NAIA), the United States Collegiate Athletic Association (USCAA), the National Junior College Athletic Association (NJCAA), and the National Christian College Athletic Association (NCCAA). Each of these various organizations is subdivided into one to three divisions, based on the number and level of scholarships that may be provided to the athletes. Teams with more talent tend to win over teams with less talent.
