2023–24 Dallas Mavericks season

The 2023–24 Dallas Mavericks season was the 44th season for the franchise in the National Basketball Association (NBA). This was also the final season in which Mark Cuban was the sole owner of the Mavericks; during the season, Cuban transitioned to a minority ownership stake, and Miriam Adelson and Patrick Dumont became majority owners of the franchise.

At the February 8 trade deadline, the Mavericks were eighth in the Western Conference with a 28–23 record when they acquired center Daniel Gafford from the Washington Wizards and forward P. J. Washington from the Charlotte Hornets. The team went 22–9 after the deadline and finished fifth in the West. The Mavericks improved upon their 38–44 record from the 2022–2023 season, qualified for the playoffs, and won the Southwest Division title.

The Mavericks defeated the Los Angeles Clippers and the top-seeded Oklahoma City Thunder each in six games to advance to their second Western Conference Finals appearance in three seasons. In the Conference Finals, the team defeated the Minnesota Timberwolves in five games to advance to the 2024 NBA Finals. The Mavericks' NBA Finals appearance was the third in the franchise's history and the team's first in 13 years since winning its lone NBA title in 2011. In the Finals, the Boston Celtics defeated the Mavericks in five games.

The Dallas Mavericks drew an average home attendance of 20,217 in 41 home games in the 2023–24 NBA season, the 2nd highest in the league.

The Mavericks entered this draft with a first-round pick. The New York Knicks held about 20.2% chance of acquiring the first-round pick; however, Dallas retained it after falling within the top ten in the lottery. Dallas had also traded their second-round pick to the Oklahoma City Thunder in 2020, which was eventually used by the Denver Nuggets in the draft, satisfying a condition that awarded Denver the second-best selection among Oklahoma City, the Washington Wizards, and the better of the Miami Heat or Dallas picks after Dallas finished the previous season worse than Miami and between Washington and Oklahoma City.

The Mavericks used their only selection to select Cason Wallace but later traded his draft rights to Oklahoma City for the draft rights to Dereck Lively II, the 12th overall pick.

The Mavericks faced the Minnesota Timberwolves twice in Abu Dhabi, United Arab Emirates. The remainder of the schedule was announced on August 30, 2023.

The schedule was announced on August 18, 2023.

This was the first regular season where all the NBA teams competed in a mid-season tournament setting due to the implementation of the 2023 NBA In-Season Tournament. During the in-season tournament period, the Mavericks competed in Group B of the Western Conference, which included the defending champion Denver Nuggets, the Los Angeles Clippers, the New Orleans Pelicans, and the Houston Rockets.
