The 1971 Grand Prix motorcycle racing season was the 23rd 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 9 May, with Austrian Grand Prix and ended with Spanish Grand Prix on 26 September.

Season summary Giacomo Agostini would claim his tenth world championship in 1971, passing Carlo Ubbiali and Mike Hailwood as the all time championship leader. However, after the death of Count Domenico Agusta in February 1971, MV Agusta's focus turned to the aviation industry. The Count's passion for motorcycle racing had been the driving force behind the MV Agusta team, and without his presence, the racing team's importance within the company began to wither.

Angel Nieto challenged for the 50cc and 125cc titles however, a crash in the final 50cc race handed the title to Dutchman Jan de Vries. Nieto was able to claim the 125 crown over a young Barry Sheene. Phil Read captured the 250 championship on a private Yamaha-powered Eric Cheney-designed chassis, after falling out with the Yamaha factory. The 1971 250cc East German Grand Prix was notable for the incident that occurred after the race victory by West German rider Dieter Braun. As Das Lied der Deutschen (the West German national anthem), was being played during the winner's ceremony, the East German crowd began singing the words to the anthem. The SED officials reacted by making the East German Grand Prix open only to Eastern Bloc competitors beginning in .

Agostini's record setting winning streak ended at the 1971 Isle of Man TT when his MV Agusta broke down on the first lap of the Junior TT. From the beginning of the season to the 1971 Isle of Man TT, Agostini won every single race he contested in the 350cc and 500cc classes. By that point, he had won 58 consecutive races, including 26 in the 350cc class and 32 in the 500cc class. Agostini won the 350 title for the fourth year in a row but a newcomer served notice when young Finn, Jarno Saarinen, won his first Grand Prix at the Czechoslovak round then won again in Italy as Yamaha continued to close the performance gap to the dominant MV Agusta team.

Agostini had things his way in the 500cc class, winning the first eight rounds of the eleven race series against minimal factory-sponsored opposition. For the second consecutive year a New Zealand rider finished second in the premier class – Ginger Molloy in and Keith Turner in 1971. Jack Findlay's victory at the 1971 Ulster Grand Prix not only marked the first victory for a Suzuki motorcycle in the premier 500cc class, but also the first-ever 500cc class victory for a motorcycle powered by a two stroke engine.Jack Findlay obituary - The Telegraph Kawasaki won their first 500cc class victory at the season ending Spanish Grand Prix at Jarama when Dave Simmonds won the race after Agostini sat out the event after already winning the championship. The inaugural Austrian Grand Prix was held at the new high-speed Salzburgring.
