The 2023 AMA Supercross Championship was the 50th season of off-road stadium motorcycle racing in the United States. Comprising 17 rounds, the series ran from January until May, crowning supercross champions in both the 250cc and 450cc classes, concluding with the Salt Lake City round on May 13.

The 2023 season was the first 450cc supercross championship for Chase Sexton. This was also the first 4 stroke, 450cc championship for Honda and the first time in 20 years that Honda won the premier class of supercross since Ricky Carmichael in 2003

The championship formed the first part of the inaugural SuperMotocross World Championship.
