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.

[1] Since then, Wimille wasn't in danger to win the race.
