2023 FIM Supercross World Championship

The 2023 FIM Supercross World Championship is a supercross series sanctioned by the Fédération Internationale de Motocyclisme (FIM) as the world championship of the sport. This is the second season that the championship is being organized by Australian promoter SX Global. Ken Roczen is the reigning champion in the WSX class for 450cc motorcycles, whilst Shane McElrath is the reigning champion in the SX2 class.

Ultimately, many of the initially scheduled rounds were later cancelled, producing a three round series. Roczen was able to successfully defend his title in the WSX championship, whilst it was Max Anstie who triumphed in SX2 where he became the first British champion of an FIM-sanctioned supercross world championship.

Calendar and results
The 2023 season is scheduled to have 6 events in Europe, Canada, Singapore, UAE and Australia. A French round was initially meant to be part of the calendar, but was later replaced by the round in UAE.
