1964 Grand Prix motorcycle racing season

The 1964 Grand Prix motorcycle racing season was the 16th 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 2 February, with United States Grand Prix and ended with Japanese Grand Prix on 1 November.

Mike Hailwood sprinted to another 500 class win for MV Agusta, winning the first six races of the year and seven races overall. Honda's Jim Redman won all eight 350 class races against only token factory opposition.

The 250 class proved to be more difficult as Yamaha's Phil Read battled Redman all season long, with Read finally coming out on top, winning five races to Redman's three. Luigi Taveri won the 125 title for Honda while Suzuki's Hugh Anderson fought a season-long battle with Honda's Ralph Bryans to retain his 50cc crown.
