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the NIT was once considered the most prestigious post-season showcase for college basketball before its status was superseded in the mid-1950s by the NCAA Division I men's basketball tournament.
