Pierre "Pagnibon" Boncompagni (19 May 1913 – 7 June 1953) was a French racing driver, best remembered for winning the 1951 Tour de France Automobile.

[4] In 1950, he purchased a Talbot-Lago T150C SS, chassis number 90120, and would drive it under the entry Ecurie Nice to considerable success over the next two years.

[16] He came within minutes of winning the 12 Hours of Hyères [fr], only for mechanical failure to strike within touching distance of the finish.

[3] Boncompagni hired a Ferrari 212 Export (serial number 0078E) from Luigi Chinetti and won the first edition of this revived event alongside navigator Alfred Barraquet.

Chinetti later exported the car to the United States in order to support his young protégé Phil Hill in club racing events.

[43][44] He drove it to second in the Coupes de Vitesse,[45] and won the 3 Hours of Algeria under the Ecurie Côte d'Azur banner.

[46] Boncompagni purchased a 340 MM Touring Spyder, serial number 0268AM, and drove it to victory in the Spring Cup at Montlhéry.

On the 34th lap, shortly before 8 a.m., he lost control of his car at a high-speed bend near the hippodrome on the easternmost part of the street circuit.

A one-minute silence was held after the race's conclusion in remembrance of Boncompagni and of Jean Heurtaux, the winner of the 1952 edition who had been killed four weeks earlier in a hillclimb near Saint-Étienne.

It has been suggested that the surname Boncompagni was notorious in France after he had acted as a collaborationist during the Second World War, which led him to avoid using it for his racing exploits.
