The 2019–20 Oklahoma City Thunder season was the 12th season of the franchise in Oklahoma City and the 53rd in the National Basketball Association (NBA). This was the Thunder's first season since 2007–08 without Russell Westbrook, as he was traded to the Houston Rockets for Chris Paul and future draft picks on July 11, 2019. The trade reunited Westbrook with former Thunder teammate James Harden, who had played for the team from 2009 to 2012. The trade also marked Chris Paul's first time since 2006–07 playing in Oklahoma City after playing his first two seasons there when he was a member of the New Orleans Hornets (the Hornets temporarily relocated to Oklahoma City for two seasons following the destruction caused by Hurricane Katrina in New Orleans). This trade was preceded by a trade where Paul George was sent to the Los Angeles Clippers for Danilo Gallinari, Shai Gilgeous-Alexander, and a record 5 future 1st-round draft picks on July 7.

The season was suspended by the league officials following the games of March 11 after it was reported that Rudy Gobert tested positive for COVID-19. The Thunder were one of the 22 teams invited to the NBA Bubble on June 4.

The Thunder faced the Rockets in the first round. However, they lost in a decisive game 7, extending the Thunder's postseason series victory drought to 4 seasons. Despite their loss, the Thunder set some records during the series, such as Chris Paul becoming the oldest player to record a triple-double, and rookie Luguentz Dort joined LeBron James and Kobe Bryant as the only players 21 years old or younger to score over 25 points in a game 7 playoff game.

Until 2024, this season marked the last time the Thunder made the playoffs.

After 5 years as head coach, Billy Donovan’s contract was not renewed following the season, and both sides agreed to mutually part ways.

Previous season The Thunder finished the 2018–19 season 49–33 to finish in fourth place in the Northwest Division, sixth in the Western Conference and qualified for the playoffs.

After falling to the Utah Jazz led by rookie Donovan Mitchell in the 2018 NBA Playoffs, the Thunder faced personnel decisions after acquiring Paul George and Carmelo Anthony in the offseason. Coming off his lowest scoring season, the Thunder traded Anthony to the Atlanta Hawks for Dennis Schröder, placing Schröder into a sixth man role. After the season ended, Anthony rejected the idea of coming off the bench while preferring to play more with the ball in his hands. In free agency, the Thunder re-signed George to a four-year, $137 million deal to stay with spending the year convincing their star to stay.

Offseason

Draft picks

Round Pick Player Position Nationality College 1 21 Brandon Clarke Power Forward Canada Gonzaga Darius Bazley The Thunder had only their own first-round pick entering the draft. The Thunder traded their 2019 second-round pick in the Hamidou Diallo trade from the Charlotte Hornets back in 2018. On draft night, the Thunder traded the draft rights to Brandon Clarke, the twenty-first pick, to the Memphis Grizzlies in exchange for the draft rights to Darius Bazley, the twenty-third pick, and a 2024 second-round pick. At the conclusion of player acquisitions and transactions on 2019 NBA draft night they ended with adding Princeton High School forward Darius Bazley.

Trades

On July 6, the Thunder traded the draft rights to Brandon Clarke, the twenty-first pick, to the Memphis Grizzlies in exchange for the draft rights to Darius Bazley, the twenty-third pick, and a 2024 second-round pick. On July 6, it was reported that the Thunder traded Paul George to the Los Angeles Clippers in exchange for a record-setting of draft choices after free agent Kawhi Leonard signed with the Clippers, which was finalized on July 10. Leonard had spent the offseason recruiting George, who reportedly requested a trade to join Leonard and the Clippers. The Thunder traded George post-extension to the Los Angeles Clippers in exchange for Shai Gilgeous-Alexander, Danilo Gallinari, a 2021 first-round pick via MIA, a 2022 first-round pick via LAC, a 2023 first-round pick via MIA, rights to swap 2023 first-round picks with LAC, a 2024 first-round pick via LAC, rights to swap 2025 first-round picks with LAC and a 2026 first-round pick via LAC. George joined the Clippers coming off of being named to his first All-NBA First Team, a finalist for the Defensive Player of the Year Award, earning All-Defensive First Team honors and finishing third for the NBA Most Valuable Player award. Following George's trade request, Russell Westbrook's future with the Thunder was "certainly in question." It was reported that the Thunder would also trade Jerami Grant to the Denver Nuggets in exchange for a 2020 first-round pick, which was finalized on July 8. By trading Grant, the Thunder saved $39 million in salary and tax.

On July 11, it was reported that the Thunder traded Russell Westbrook to the Houston Rockets in exchange for Chris Paul, rights to swap 2021 first-round picks, a 2024 first-round pick, rights to swap 2025 first-round picks and a 2026 first-round pick, which was finalized on July 16. With George departing, Westbrook's future with the Thunder was in jeopardy and the two sides worked together on a trade. Sam Presti worked with Westbrook and his representatives to honor Westbrook's desires of playing with the Houston Rockets to reunite with James Harden. Since the 2019 NBA draft, the Thunder had accumulated eight first-round picks in embracing a full rebuild of the team. Having spent eleven seasons with the Thunder, Westbrook left Oklahoma City as the franchise's all-time leader in points, second in assists, third in rebounds and steals. Westbrook was the NBA Most Valuable Player in the 2016-17 season, an eight-time All-Star, All-NBA First Team honors twice, All-NBA Second Team honors five times, as well as accruing two scoring titles and an assists leader title.

Patton spent the 2018-19 season with the Philadelphia 76ers. To fill in the other two-way slot, Devon Hall signed a two-way contract with the Thunder on September 4.
