The 1954 Grand Prix motorcycle racing season was the sixth F.I.M. Road Racing World Championship Grand Prix season. The season consisted of nine Grand Prix races in five classes: 500cc, 350cc, 250cc, 125cc and Sidecars 500cc. It began on 30 May, with French Grand Prix and ended with Spanish Grand Prix on 3 October.
The Constructors' titles for all classes were not recognized by the Federation following a political crisis with the constructors (represented by the International Permanent Bureau of Motorcycle Manufacturers) concerning the number of races to be held during the season and the abolition of the riders' championship.
