Have the Thunder won an NBA championship? Complete finals, playoff history for Oklahoma City

To say the Thunder have been in Oklahoma City for less than 20 years, the franchise has experienced its fair share of large-scale success.

During its time in OKC, the Thunder have rostered a host of all-time greats and, as a result, made several deep runs in the NBA Playoffs.

Led by MVP hopeful Shai Gilgeous-Alexander, the Thunder won 68 games in 2024-25 and capped it with a championship after defeating the Pacers in seven Finals games.

Have the Thunder won an NBA championship?

As of June 22, 2025, the Thunder won the first NBA title in the current iteration of their franchise, defeating Indiana in Game 7 to clinch a Finals win. They did technically have a previous title, but it was not when the franchise was known as the Thunder.

The NBA recognizes the Seattle Supersonics' 1979 NBA title as a part of the Thunder franchise history. The SuperSonics relocated to Oklahoma City in 2008 and rebranded to become the Thunder for the 2008-09 season.

While the league recognizes the SuperSonics and Thunder as one franchise, Oklahoma City does not technically claim the title. There is no championship banner at the Paycom Center, and the team does not have a championship-signifying gold tab on the neckline of their jerseys.

If the NBA were to return to Seattle with an expansion team, the Thunder would reportedly cede the SuperSonics era of franchise history (1967-2008) to the new franchise.

Nonetheless, the Thunder secured a more-official championship than the previous SuperSonics one in 2025 led by Gilgeous-Alexander.

How many championships have the Thunder won?

The Thunder have officially won two championships.

While known as the SuperSonics, the franchise defeated the Washington Bullets (now Wizards) in five games in the 1979 NBA Finals. The franchise captured a title after losing in the Finals the previous year and would not return to that stage for 17 years.

Hall of Fame head coach Lenny Wilkens led the 1979 Sonics and Hall of Famer Dennis Johnson was named Finals MVP with averages of 22.6 points, 6.0 rebounds, 6.0 assists, 2.0 blocks, and 1.8 steals over the series. The roster also featured Jack Sikma, Paul Silas, and Gus Williams.

Then, in 2025, the Thunder won a title for the first time since moving to Oklahoma City. They took down the Pacers in seven games, with a young core of Gilgeous-Alexander, Chet Holmgren and Jalen Williams paving the way.

When was the last time the Thunder played in the NBA Finals?

The Thunder's most recent NBA Finals appearance was in 2025 against the Pacers. Before then, it was 2012 against the Heat. Miami won that series, 4-1.

Oklahoma City had not been to the NBA Finals since that series until 2025, though it came close in 2016. After building a 3-1 series lead in the 2016 Western Conference Finals, the Thunder dropped three consecutive games to be eliminated in seven.

The franchise's run to the 2025 conference finals also snapped a nine-year drought from that stage.
