The 2022–23 NBA G League season was the 22nd season of the NBA G League, the minor league basketball league of the National Basketball Association (NBA). For the second consecutive season, the schedule was split into two parts: the 18-game Showcase Cup began on November 4, 2022, followed by a 32-game regular season tipped off on December 27.^[1] The Delaware Blue Coats defeated the Rio Grande Valley Vipers 2–0 in the 2023 NBA G League Finals.

The Showcase Cup began on November 4, 2022, and it will end with a single-elimination tournament to crown a champion at the G League's Winter Showcase from December 19 to 22. During the Showcase Cup, teams are separated into four regional pods and play 16 games against one another in each respective NBA G League markets. The teams with the best winning percentage in each regional pod, along with the next four teams across the league with the best win-percentages, will advance to compete for the Showcase Cup during Winter Showcase.^[1]
