The Oklahoma City Thunder are a professional basketball team based in Oklahoma City, Oklahoma. They play in the National Basketball Association (NBA) and are a member of the NBA Western Conference's Northwest Division. The Thunder were founded in 1967 as the Seattle SuperSonics as one of two franchises that joined the NBA in the 1967âÂÂ68 season. The SuperSonics moved to Oklahoma City after the 2007âÂÂ08 season. The records from the decades the team was in Seattle are still attached to the Oklahoma City history, but will be transferred back to a new Seattle SuperSonics team when and if NBA expansion there is approved.
Overall, the Thunder have qualified for the NBA playoffs on ten occasions after being relocated from Seattle (22 times as the SuperSonics). They reached the Western Conference finals seven times, reaching the NBA Finals in 1978, 1979, 1996, 2012 and 2025 winning their only championship while in Seattle during the 1979 NBA Finals against the Washington Bullets and won again in Oklahoma City in the 2025 NBA Finals against the Indiana Pacers.
