The 1946 Roussillon Grand Prix (formally the I Grand Prix du Roussillon) was a Grand Prix motor race held at Circuit des Platanes de Perpignan on 30 June 1946.
Jean-Pierre Wimille and Raymond Sommer held the race until piston troubles show up and oblige the Maserati 4CL to retire. Since then, Wimille wasn't in danger to win the race.
