2024–25 Oklahoma City Thunder season

The 2024–25 Oklahoma City Thunder season was the 17th season of the franchise in Oklahoma City and its 59th season in the National Basketball Association (NBA).

The Thunder advanced to the 2024 NBA Cup knockout stage as the winner of West Group B after finishing the group stage with a 3–1 record and winning the head-to-head tiebreaker over the Phoenix Suns by virtue of their group-stage victory on November 15. They would defeat the Dallas Mavericks in the quarterfinals and the Houston Rockets in the semifinals before losing to the Milwaukee Bucks in the championship game.

On March 12, 2025, the Thunder clinched their 2nd consecutive playoff berth with a win over the Boston Celtics. On April 10, following a loss by the Cleveland Cavaliers, the Thunder won the Maurice Podoloff Trophy and home-court for the entire playoffs for clinching the best record in the NBA for the first time in franchise history. The Thunder outscored their opponents by 12.9 points per game during the regular season, which was more than half a point better than the previous record holder 1971–72 Los Angeles Lakers' 12.3 points per game.

On April 20, the Thunder defeated the Memphis Grizzlies 131–80, the biggest Game 1 victory in playoff history. Team star Shai Gilgeous-Alexander won the 2025 NBA MVP award, becoming the third recipient in franchise history; Kevin Durant and Russell Westbrook previously won for the Thunder in 2014 and 2017, respectively. On May 28, 2025, the Thunder defeated the Minnesota Timberwolves in Game 5 of the Western Conference Finals to clinch their first NBA Finals berth since 2012 and their second in Oklahoma City. They would go on to defeat the Indiana Pacers in seven games, winning their second NBA championship, and their first since 1979, when they were known as the Seattle SuperSonics. In Game 7, they were the first team to score 100 points or more in Game 7 of the NBA Finals since the Los Angeles Lakers and Detroit Pistons did so in 1988.

At an average age of 25.6 years old, they were the second youngest team to win an NBA championship, behind only the 1976–77 Portland Trail Blazers. Their Finals victory was the first championship of any major professional sport in the state of Oklahoma. The Thunder also became the fourth team in NBA history to win 84 games or better in a single season, including playoff victories (the Chicago Bulls did it twice, followed by the Golden State Warriors). They also became the first team in NBA history to play for the NBA Cup and the NBA Finals in the same season.

Following the Thunder's championship victory, several politicians across Oklahoma celebrated, including Oklahoma City mayor David Holt, Oklahoma governor Kevin Stitt, United States representative Stephanie Bice, and United States senator James Lankford.

The Oklahoma City Thunder drew an average home attendance of 17,972, the 16th-highest of all NBA teams.
