The 1991 Vitesse du Mans motorcycle Grand Prix was a one-off race and the penultimate round of the 1991 Grand Prix motorcycle racing season. It took place on the weekend of 6–8 September 1991 at the Bugatti Circuit located in Le Mans. France.

Originally meant to be held in Brazil, that race was cancelled for safety reasons, so the FIM decided to add a second French round. It is the only time in FIM Grand Prix motorcycle racing history two rounds were held in France during a season. The race's name was used for this race only, after the European Grand Prix moniker had been used for a race in Jarama that replaced the Yugoslavian race.
