2018 NBA Summer League

The 2018 NBA Summer League consisted of three pro basketball leagues organized by the National Basketball Association (NBA): the Sacramento Kings's California Classic Summer League, Utah Jazz Summer League, and Las Vegas Summer League.

The Sacramento Kings hosted their own summer league event called the California Classic at the Golden 1 Center in Sacramento. The event was scheduled to take place before the Las Vegas Summer League began, with the teams in place for the event involving the Kings, Los Angeles Lakers, Golden State Warriors, and Miami Heat. Eight days later, the Kings confirmed that their own Summer League event (titled the California Classic Summer League) would take place July 2–5, 2018 (taking a day off to celebrate the Fourth of July), replacing the Orlando Pro Summer League. On May 14, 2018, the Kings confirmed that report.

Four teams participated in the round-robin format of the Utah Jazz Summer League from July 2 to July 5, 2018. All four teams (Utah Jazz, Atlanta Hawks, Memphis Grizzlies, and San Antonio Spurs) also participated in the Las Vegas Summer League.

The 2018 Las Vegas NBA Summer League was the official 2018 summer league of the National Basketball Association. The league was held at the Thomas and Mack Center and Cox Pavilion in Las Vegas, Nevada, on the campus of University of Nevada, Las Vegas. It began on July 6 and ended on July 17. For the first time in league history, all 30 teams participated. With every team participating, the event expanded to 82 games in 12 days. Teams competed in a tournament-style schedule in three preliminary games before seeding in a tournament; each team played at least five games and as many as eight games. The event concluded with the 2018 NBA Summer League Championship game on July 17.
