The 1970 Grand Prix motorcycle racing season was the 22nd F.I.M. Road Racing World Championship Grand Prix season. The season consisted of twelve Grand Prix races in six classes: 500cc, 350cc, 250cc, 125cc, 50cc and Sidecars 500cc. It began on 3 May, with West German Grand Prix and ended with Spanish Grand Prix on 27 September.

This is the most recent season before 2024 that the Japanese manufacturers failed to score a single win in the premier class.

Season summary The MV Agusta team continued to dominate as Giacomo Agostini won his fifth consecutive 500cc world championship against minimal opposition from other manufacturers. From 1968 to 1970, Agostini and MV Agusta were so dominant that Agostini won every single race he contested in the 350cc and 500cc classes. However, Japanese manufacturers continued to improve two-stroke engine technology. In 1970, Kawasaki began to sell the Kawasaki H1R to privateer racing teams. The H1R was the first multi-cylinder two stroke racing motorcycle to be sold commercially. Ginger Molloy rode one of the Kawasakis to a second-place finish behind Agostini in the 500cc championship.

Life was harder for Agostini in the 350 class as Kel Carruthers and Renzo Pasolini on Benellis and Rod Gould on a factory Yamaha gave him a battle on more than one occasion. Gould would take the 250 title for Yamaha, battling Carruthers for the entire season. German Dieter Braun would give Suzuki the 125 crown while Derbi mounted Angel Nieto claimed the 50cc class for the second year in a row.

Braun's victory at the 1970 Isle of Man TT was notable because he was one of only seven riders to have won an Isle of Man TT race in their first attempt. Due to the circuit's 37.7 mile length, it usually takes competitors two or three attempts before they learn its nuances. There were six fatalities among the competitors at the Isle of Man TT races, including world championship contender Santiago Herrero, making 1970 the deadliest year in the history of the event.
