Louis Claude Rosier (5 November 1905 – 29 October 1956) was a French racing driver and motorsport executive, who competed in Formula One from 1950 to 1956. In endurance racing, Rosier won the 24 Hours of Le Mans in 1950 in a privateer Talbot-Lago T26C-GS.
Rosier competed in Formula One under his own Écurie Rosier banner, making privateer entries in machinery from Talbot-Lago, Ferrari, and Maserati; he also competed for the works teams of Talbot and Maserati, the former of which he scored back-to-back podium finishes with at the Swiss and Belgian Grands Prix in 1950.
Rosier competed in nine editions of the 24 Hours of Le Mans between 1938 and 1956, winning in 1950 alongside his son Jean-Louis Rosier, which remains the only father-and-son victory in Le Mans history. In October 1956, Rosier died as a result of injuries sustained whilst sportscar racing in a Ferrari 750 Monza at Montlhéry.
