2015–16 Oklahoma City Thunder season

The 2015–16 Oklahoma City Thunder season was the 8th season of the franchise in Oklahoma City and the 50th in the National Basketball Association (NBA), and the first under head coach Billy Donovan. After coming just short of making the playoffs the previous season, the Thunder won the Northwest Division and clinched the third seed in the Western Conference. In the playoffs, the Thunder defeated the Dallas Mavericks in five games in the First Round, and the San Antonio Spurs in six games in the Semifinals (which was also Tim Duncan's final NBA game) before reaching the Western Conference finals for the fourth time in a span of six seasons, but were eliminated by the defending NBA champion Golden State Warriors in seven games after leading the series 3–1.

After almost pulling what would've been one of the biggest upsets in professional sports history over the 73–9 Warriors, the Thunder missed out on what would’ve been their first Finals appearance since 2012. The Warriors would go on to lose in seven games against the Cleveland Cavaliers in the NBA Finals after they too led the series 3–1. After the season, Kevin Durant controversially left the team in free agency for the Golden State Warriors.

After this season, the Thunder would not reach the Western Conference Finals again until 2025, where they would win the conference and the NBA Championship.

The Thunder finished the 2014–15 season 45–37 to finish in second place in the Northwest Division, ninth in the Western Conference and failed to qualify for the playoffs. This marks the second season that the Thunder failed to qualify for the playoffs since moving to Oklahoma City. Following the season, head coach Scott Brooks was fired on April 22, 2015.

Cameron Payne was selected 14th overall by the Oklahoma City Thunder.

The Thunder had their own first-round pick and second-round pick entering the draft. The Thunder ended 2015 NBA draft night with Murray State guard Cameron Payne and Kentucky center Dakari Johnson.

On June 25, the Thunder traded Jeremy Lamb to the Charlotte Hornets in exchange for Luke Ridnour and a future 2016 second-round pick in an effort for payroll relief. Lamb was originally acquired in the James Harden trade back in 2012. Five days later, Ridnour was traded again along with cash considerations to the Toronto Raptors in exchange for the draft rights to Tomislav Zubcic and a trade exception.

On July 14, the Thunder traded Perry Jones, a 2019 second-round pick, and cash considerations to the Boston Celtics in exchange for a protected 2018 second-round pick and a trade exception in another effort for payroll relief. By trading Jones' $2 million, the Thunder cleared $5 million in luxury tax payments.

Josh Huestis was signed to a rookie deal after being the first "domestic draft-and-stash."

For this offseason, free agency began on July 1, 2015, while the July moratorium ended on July 7. Enes Kanter and Kyle Singler were set to hit restricted free agency. On July 1, it was reported that Kyle Singler agreed to a five-year, nearly $25 million deal to stay with the Thunder, which he later signed on July 9. On July 9, Enes Kanter signed a four-year, $70 million deal with the Portland Trail Blazers. However, on July 12, the Thunder exercised its right of first refusal and matched the Trail Blazer's offer sheet to re-sign Kanter.

On July 30, Josh Huestis signed a rookie deal with the Thunder. Huestis was originally selected 29th overall in the 2014 NBA draft but became the first "domestic draft-and-stash" after working out a predraft arrangement with the Thunder to not sign his guaranteed rookie-scale deal. Huestis spent the 2014-15 NBA season with the Oklahoma City Blue.

After the Thunder failed to make the 2015 NBA Playoffs, head coach Scott Brooks was fired on April 22, 2015, after seven seasons with the team. Brooks was named head coach of the Thunder on April 15, 2009, taking over for P.J. Carlesimo after serving as interim head coach during the 2008–09 season. Brooks accumulated a 338-207 (.620) record, named the 2009–10 season NBA Coach of the Year, made three appearances in the Western Conference finals (2011, 2012, 2014) and an appearance in the 2012 NBA Finals.

On April 30, the Thunder hired Billy Donovan, formerly with the Florida Gators, as head coach. Donovan became the third head coach of the Thunder since moving to Oklahoma City. Donovan led the Gators to two national championships, four trips to the Final Four, and accumulated a 467-186 (.715) record.

On June 29, the Thunder announced Monty Williams, Maurice Cheeks, and Anthony Grant as assistant coaches and Billy Schmidt as quality control coach. Williams joins the Thunder after serving five seasons as the head coach of the New Orleans Pelicans leading the Pelicans to a playoff appearance in the 2014–15 season. Cheeks re-joined the Thunder after serving as the head coach of the Detroit Pistons during the 2013–14 season. Grant joins the Thunder after serving six seasons as the head coach of the Alabama Crimson Tide. Schmidt joins the Thunder after serving last season under Billy Donovan at the University of Florida.
