2023–24 NCAA Division I men's basketball season

The 2023–24 NCAA Division I men's basketball season began on November 6, 2023. The regular season ended on March 17, 2024, with the 2024 NCAA Division I men's basketball tournament beginning with the First Four on March 19 and ending with the championship game at State Farm Stadium in Glendale, Arizona, on April 8.

Rule changes
On May 5, 2023, the NCAA Basketball Rules Committee proposed a suite of rule changes for the 2023–24 season. These changes were approved by the Playing Rules Oversight Panel during its June 8 conference call.
 * A defender near the basket must be in position to draw a charge before the offensive player plants his foot to jump during a field goal attempt. If the defender arrives after the shooter has planted his foot, the officials are to call a blocking foul if contact occurs.
 * Prerecorded or live video can be transmitted to the bench area during the game, on an optional basis. This had been an experimental rule since 2021–22, but is now permanent.
 * Officials will be able to review basket interference or goaltending calls during the next media timeout to ensure the call's accuracy, as long as they were made during play. Review is immediate if a foul is called on a shot that ended with basket interference or goaltending.
 * Non-student bench personnel will be allowed to serve as peacekeepers in any altercation.
 * If a coach requests a review of an out-of-bounds play in the last two minutes, that team will be charged a timeout if the challenge is unsuccessful.
 * The shot clock will reset to 20 seconds for all offensive rebounds when the original shot has touched the rim.
 * If a player is called for a foul, and replay officials see that the foul is the direct result of a flagrant foul against the player who was originally charged with the foul, officials can rescind the foul on the victim of the flagrant foul.
 * A timeout can be granted when a player has possession of the ball while airborne.
 * A player will be disqualified if he commits three flagrant 1 fouls in a game, regardless of his overall foul count.
 * Red and amber lights can now be placed on the backboard.
 * Schools will no longer have to apply for a waiver to allow players to use religious headwear that is safe for competition.
 * All jersey numbers from "0" to "99," including "00," will be allowed, although with the restriction that teams are allowed to use "0" or "00," but not both at the same time. It is the first time that players are allowed to wear the digits "6" through "9" on their uniforms since those digits were prohibited prior to the 1957–58 season as a means of simplifying referees' hand signals to the scorer's table after calling a foul.
 * Conferences will be allowed to continue using an experimental rule that allows for media timeouts to be taken at the first dead ball after the 17-, 14-, 11-, 8-, and 4-minute marks of the second half. This rule may also be used in the 2024 NIT, subject to approval by the NCAA's NIT board.
 * Also, subject to NIT board approval, the free-throw lane may be widened to 16 feet in the 2024 NIT.

Season headlines

Conference membership changes
Nineteen schools joined new conferences, became independents, or dropped athletics.

The 2023–24 season was the last for 20 Division I schools in their then-current conferences and two Division II schools in their then-current conferences before reclassification to Division I. It was also Chicago State's last season as a Division I independent.

In addition to the above changes, the Indiana University and Purdue University systems will split IUPUI into separate IU- and Purdue-affiliated institutions at the end of the 2023–24 academic year, a move similar to the two systems' dissolution of their joint Fort Wayne campus in 2018. The IUPUI athletic program will be transferred to the new IU Indianapolis, maintaining IUPUI's memberships in Division I and the Horizon League. Shortly before the split became official, the IUPUI athletic website adopted a new brand of IU Indy.

New arenas

 * Austin Peay left the on-campus Winfield Dunn Center for the new F&M Bank Arena in downtown Clarksville, Tennessee after 49 seasons. The new arena opened on July 15, 2023. The first basketball event in the new arena was a joint practice by the Peay men's and women's teams on October 26, 2023. This was followed by an 82–43 exhibition win against Tennessee Tech on November 1. The first official games were a men's and women's doubleheader on January 6, with the men defeating NAIA Life University 90–72 in the second game.

 * Vermont was originally slated to open the new Tarrant Event Center, the replacement for Patrick Gym, in 2021. However, the new arena has since been placed on indefinite hold. Construction was initially halted by COVID-19. With the Tarrant Center being part of a much larger upgrade of UVM's athletic and recreation facilities, UVM chose to prioritize a new student recreation center. Construction of the Tarrant Center is now being hampered by increased borrowing costs.

Upsets
An upset is a victory by an underdog team. In the context of NCAA Division I men's basketball, this generally constitutes an unranked team defeating a team currently ranked in the top 25. This list will highlight those upsets of ranked teams by unranked teams as well as upsets of No. 1 teams. Rankings are from the AP poll. Bold type indicates winning teams in "true road games"—i.e., those played on an opponent's home court (including secondary homes). Italics type indicates winning teams in an early season tournament (or event). Early season tournaments are tournaments played in the early season. Events are the tournaments with the same teams in it every year (even rivalry games).

In addition to the above listed upsets in which an unranked team defeated a ranked team, there have been five non-Division I teams that defeated a Division I team so far this season. Bold type indicates winning teams in "true road games"—i.e., those played on an opponent's home court (including secondary homes).

Conference winners and tournaments
Each of the 32 Division I athletic conferences ended its regular season with a single-elimination tournament. The team with the best regular-season record in each conference receives the number one seed in each tournament, with tiebreakers used as needed in the case of ties for the top seeding. Unless otherwise noted, the winners of these tournaments received automatic invitations to the 2024 NCAA Division I men's basketball tournament.

Postseason tournaments
The NCAA Tournament tipped off on March 19, 2024 with the First Four in Dayton, Ohio, and will conclude on April 8 at State Farm Stadium in Glendale, Arizona. A total of 68 teams entered the tournament. Thirty-two of the teams earned automatic bids by winning their conference tournaments. The remaining 36 teams were granted "at-large" bids, which are extended by the NCAA Selection Committee.

Tournament upsets
Per the NCAA, an upset occurs "when the losing team in an NCAA tournament game was seeded at least five seed lines better than the winning team." The 2024 tournament had nine upsets, with seven in the first round, one in the Sweet Sixteen, and one in the Elite Eight.

National Invitation Tournament
After the NCAA Tournament field is announced, the National Invitation Tournament invites 32 teams to participate, reducing the field's size from 40. For the first time in recent years, automatic bids will not be granted to regular-season conference champions that fail to reach the NCAA tournament. Instead, after the NCAA tournament bracket is filled, the NCAA will award NIT bids to the top two remaining teams in NET rating from each of the so-called "Power 6" conferences (ACC, Big East, Big Ten, Big 12, Pac-12, and SEC). All games before the semifinals will be at campus sites, with the semifinals and final at Hinkle Fieldhouse in Indianapolis.

College Basketball Invitational
After the NCAA Tournament field was announced, the College Basketball Invitational invited 15 teams to participate.

CollegeInsider.com Postseason Tournament
