Guy Fréquelin (born 2 April 1945 at Langres) is a French former rally and sports car driver.

Perhaps Fréquelin's finest hour as a driver came when he finished runner-up only to Ari Vatanen, alongside then-navigator Jean Todt, at the wheel of a briefly competitive Sunbeam Lotus Talbot in the driver's classification of the 1981 World Rally Championship.

As part of a team which included the French racing drivers, Jean-Pierre Jabouille, Jacques Laffite, Patrick Depailler, Patrick Tambay, Jean-Pierre Jaussaud, René Arnoux and Didier Pironi, as well as the English long distance expert Derek Bell, Fréquelin was named as the third driver for both the #7 Tambay/Jaussaud and the #16 Arnoux/Pironi machines.

Fréquelin, though, was to return to the Sarthe circuit for the 1981 race, paired with countryman Roger Dorchy in the #5 WM P79/80 Peugeot.
