The 1973 FIM Motocross World Championship was the 17th edition of the Motocross World Championship organized by the FIM and reserved for 500cc and 250cc motorcycles.
The FIM implements a new championship points scoring formula beginning in 1973. The Grand Prix races are still run with 2 heats but it is the sum of the results of each heat that counts for the final classification of the World Championship and not the points acquired at each Grand Prix.
