The 2009–10 Oklahoma City Thunder season was the 2nd season of the franchise's existence in Oklahoma City as a member of the National Basketball Association (NBA).

With NBA scoring champion Kevin Durant, second-year point guard Russell Westbrook, and forward Jeff Green leading the way, the Thunder made the playoffs as the youngest team in the NBA with the 28th highest total salary in the league. The team became the youngest NBA playoff team (23.19, using data going back to 1952) based on average age weighted by minutes played. The Thunder were then eliminated by the defending and eventual NBA champions, the Los Angeles Lakers in six games in the First Round. The 2009–10 Oklahoma City Thunder and the 2007–08 Denver Nuggets are tied at 50–32 for having the best 8th seed record in NBA history. This was also the first season for James Harden. The Thunder clinched their first playoff spot since 2005, and their first in Oklahoma City.

From a business perspective, the team began to show positive financial performance after years of losses in Seattle and a transition-cost laden 2008–09 season. In December 2009, Forbes magazine estimated the team's operating profit at $12.7 million, and estimated the overall franchise value at $310 million, good for 20th in the NBA.
