The 1951 Grand Prix motorcycle racing season was the third F.I.M. Road Racing World Championship Grand Prix season. The season consisted of eight Grand Prix races in five classes: 500cc, 350cc, 250cc, 125cc and Sidecars 500cc. It began on 8 April, with Spanish Grand Prix and ended with Nations Grand Prix on 9 September.
