The 2022–23 NCAA Division I men's basketball season began on November 7, 2022. The regular season ended on March 12, 2023, with the 2023 NCAA Division I men's basketball tournament beginning with the First Four on March 14 and ending with the championship game at NRG Stadium in Houston on April 3.

Rule changes The following rule changes were recommended by the NCAA Basketball Rules Committee to the Playing Rules Oversight Panel for the 2022−23 season: Flopping will now result in a Class B technical foul. Previously players called for flopping received a warning before a technical foul was assessed. Conferences (and the NIT) will continue to allow (on an experimental basis) the use of live and prerecorded video streams at the team bench. Conferences (and the NIT) who choose to use five electronic-media timeouts in the second half of their games will be able to experiment with a new format for granting those timeouts. Currently, for a game using five electronic-media timeouts in the second half, the rulebook prescribes that four of those occur in the same manner as in the first half—that is, at the first dead ball at or after the 16-, 12-, 8-, and 4-minute marks, or up to 30 seconds prior to those marks in specific circumstances. The fifth electronic-media timeout occurs when the first timeout requested by either team in the second half automatically becomes an electronic-media timeout. Competitions choosing to use this experimental rule will continue to have five electronic-media timeouts in the second half, but those will occur instead at or after the 17-, 14-, 11-, 8-, and 4-minute marks (or up to 30 seconds prior to those marks in specific circumstances), while the first team-requested timeout will no longer automatically become a media timeout.
