The 2022 IMSA SportsCar Championship (known for sponsorship reasons as the 2022 IMSA WeatherTech SportsCar Championship) was the 52nd racing season sanctioned by the International Motor Sports Association (IMSA), which traces its lineage back to the 1971 IMSA GT Championship. This was also the ninth season of the IMSA SportsCar Championship since the merger between the American Le Mans Series and the Rolex Sports Car Series in 2014, and the seventh under the sponsorship of WeatherTech. The series began on January 27 for the 24 Hours of Daytona, and ended on October 1 with the Petit Le Mans after 12 races.
