Pierre-André Lefaucheux (30 June 1898 – 11 February 1955) was a leading French industrialist and recipient of the Order of Liberation, awarded to heroes of France's Liberation during World War II.
Lefaucheux was the subject of the 2009 biography, Patron de Renault, Pierre Lefaucheux (1944-1955) by Cyrille Sardais.
Returning to civilian life he enrolled at the école centrale des arts et manufactures, obtaining his diploma in 1922. Lefacheux began his working life with a brief spell at the North France Railway Company, before joining in 1925 the Compagnie générale de construction de fours (General Boiler Manufacturing Company) where he would build his career until 1939, and where he became a director.
In parallel, he began in 1929 a doctoral thesis which he would submit in 1935 on the subject of “The peseta and the Spanish economy”.
After the nationalisation of the Renault automobile business Lefaucheux took charge of the company in 1945. Lefaucheux had no great passion for cars, and even after being appointed to the top job at Renault he continued, for some time, to travel to work using his preferred form of locomotion, a pedal cycle. Lefaucheux set a pattern whereby Renault, despite now being a nationalised industry, ferociously rejected management by politicians: in this he was naturally able to draw on the network of influential former resistance leaders and fighters, many now in positions of power within the Fourth Republic French state. This was important at a time when France was ruled by a strongly dirigiste government, capable of implementing the Pons Plan which reflected government determination to structure the French auto-industry according to priorities identified by politicians and civil servants. Lefaucheux's stewardship saw Renault becoming France's leading automobile manufacturer, with Lefaucheux directing the development of the commercially successful Renault 4CV — and up until the time of his death, its successor, the Renault Dauphine.
On Friday, 11 February 1955, Lefaucheux was scheduled to give a presentation to Catholic students in Strasbourg. Despite inclement icy weather, Lefaucheux, an avid motorist, decided at the last minute to travel by car — placing his suitcase not in the trunk, but on the rear seat of his Renault Frégate. Approaching Saint-Dizier from the West, on the Route Nationale 4 (N4), he encountered a detour, which at the last moment he tried to follow. The road surface was covered with black ice, the car spun, rolled over and landed on its side in a field. Though the Frégate's passenger cell was largely intact, Lafaucheux's unsecured suitcase on the rear seat had struck him in the neck, killing him instantly. In his pocket, he carried a train ticket for the trip.

By the time of his death, Lefaucheux had overseen almost the entire development of the Renault Dauphine, which would be presented at the Geneva Motor Show in March 1956. He was succeeded at Renault by the company's vice-president, Pierre Dreyfus.
A monument in Lefaucheux's memory was erected at the N4 near Saint-Dizier. The Renault Flins factory was renamed in his honor, as well as a boulevard in Le Mans. He is buried at Saint-Quentin-des-Prés, in the Oise Department.
Lefaucheux had been arrested by the Gestapo during World War II and was rescued by Marie-Hélène Postel-Vinay whom he subsequently married and by whom he was ultimately survived.
Together, Pierre and Marie-Hélène Lefaucheux became prominent members of the Resistance. Mrs. Lefaucheux later became a Member of the first Constituent Assembly (Aisne) of France, Counsel for the Republic elected by the National Assembly from 1946 to 1947, member of the French delegation to the United Nations. She was one of the fifteen founding members of the United Nations Commission on the Status of Women.

Er hat eine Fahrkarte für die Bahn in der Tasche, das Wetter ist schlecht, es wird Glatteis vorausgesagt. Doch in letzter Minute entscheidet sich LEFAUCHEUX für die Fahrt mit dem Auto. Er wirft seinen Koffer auf den Rücksitz seiner Frégate. Als die Stadt Saint-Dizier in Sicht kommt, überrascht ihn ein Schild, das eine Umleitung anzeigt. Er hätte geradeaus weiter fahren können, doch er versucht im letzten Moment der Umleitung nachzufahren. Er bremst, doch auf der Strasse ist Glatteis. Die Frégate dreht und überschlägt sich und kommt in einem Acker auf der Seite zum Liegen. Die Fahrgastzelle ist nahezu unbeschädigt. Doch der Koffer auf dem Rücksitz trifft LEFAUCHEUX im Nacken. PIERRE LEFAUCHEUX war auf der Stelle tot!"
