Final Four

• 1970 NCAA College Division basketball tournament
• 1970 National Invitation Tournament
• 1970 NAIA Division I men's basketball tournament
• 1970 National Women's Invitation Tournament

• In Iowa's 121–106 win over Notre Dame, the two teams set a tournament record for most combined points (227).
• Every game in the Mideast Regional saw at least one of the two teams score 100 points or more.
• For the second straight year, a first-time tournament participant, in this case Jacksonville, made the national championship game. Niagara and Long Beach State also made their tournament debuts this year, both of whom placed as their respective regional fourth place teams.
• This was the first of eighteen tournament appearances for Long Beach coach Jerry Tarkanian, who would go on to coach the 49ers to four straight tournament appearances, as well as the UNLV Runnin' Rebels to a national championship (1990) and four Final Fours, and Fresno State to two tournament appearances.
• The 1970 tournament is, to date, the most recent tournament appearance for Rice University. They currently hold the fifth longest active drought after Dartmouth (1959), Tennessee Tech (1963), Bowling Green and Columbia (1968) and Seattle (1969).
• Three of the Final Four teams had dominant centers that would go on to successful NBA careers; Jacksonville with Artis Gilmore, St. Bonaventure with Bob Lanier, and New Mexico State with Sam Lacey. However, UCLA would win the tournament despite losing their dominant center from the previous season (Lew Alcindor).
