1980 Grand Prix motorcycle racing season

The 1980 Grand Prix motorcycle racing season was the 32nd F.I.M. Road Racing World Championship season.

Season summary
Yamaha's Kenny Roberts claimed his third successive 500cc world championship in a season shortened by the cancellations of the Venezuelan and Austrian rounds. Randy Mamola took over at Suzuki from Barry Sheene. Kawasaki returned to the 500cc class with a monocoque, four cylinder bike for Kork Ballington. Honda soldiered on with its exotic four-stroke NR500 but began to realize it was at a disadvantage against its two-stroke opposition.

There were only six rounds in the 350cc class that saw South Africa's Jon Ekerold, a true privateer, take the championship from the Kawasaki factory-sponsored Anton Mang. Mang would take the 250cc crown from defending champion Ballington while Pier Paolo Bianchi won the 125cc title. Eugenio Lazzarini won a tight battle from Swiss Stefan Dörflinger to take the 50cc championship by only 2 points.
