The 2024 NBA Cup was a multi-stage basketball tournament played during the 2024–25 NBA season. It was the second edition of the NBA Cup. All 30 teams participated, each playing four regular season games that counted towards the tournament's group stage standings—all in the knockout round, except for the championship game. The Milwaukee Bucks defeated the Oklahoma City Thunder in the championship game. Milwaukee's Giannis Antetokounmpo was named the Most Valuable Player of the tournament.

The Los Angeles Lakers entered as the defending champions, but were eliminated in the group stage. The Indiana Pacers were also eliminated in the group stage after losses to the Miami Heat, Milwaukee Bucks, and Detroit Pistons, meaning that the championship game consisted of two new teams: the Bucks and the Oklahoma City Thunder.

The tournament's format was similar to in-season, multi-stage tournaments in European soccer.

In the group stage, each conference was divided into three groups with five teams each, for a total of six groups. Regular season games played on Tuesdays and Fridays between November 12 and December 3 counted in the regular season standings and the NBA Cup standings. Each team played one game against each of the other teams in its group, for a total of four games (two at home and two on the road).

If two or more teams in a group had equal records upon completion of group play, the following tiebreakers were applied in this order:

Note: Overtime scoring did not count towards the point differential and total points tiebreakers in the Emirates NBA Cup. A team's point differential was "0" in Group Play games that went to overtime, and a team's total points scored excluded points scored in overtime.

Each group's winner then advanced to the knockout stage, as did one wild card from each conference—the group runner-up with the best group stage record. The knockout stage was a single-elimination tournament. Quarterfinal games were played in local NBA markets on December 10 and 11, with the teams with the top two group stage records in each conference hosting, and the best team in group-play games would host the wild-card team. The semifinals were played on December 14, and the championship on December 17. The final two rounds were played at T-Mobile Arena on the Las Vegas Strip.

Quarterfinal and semifinal games counted as regular season games, affecting teams' positions in league standings, but the championship game did not. Statistics from the championship game were also not counted in regular season totals.
