Paray-Vieille-Poste is a commune in the Essonne department in Île-de-France in northern France. Paris-Orly Airport is partially located in the commune.
Inhabitants of Paray-Vieille-Poste are known as Paraysiens.
Paray-Vieille-Poste originated from the old village of Paray, which had about 60 residents in 1790. The name "Paray-Vieille-Poste" first appeared in 1923. By 1928 the population swelled to 3,000 residents. At the time streets had not yet been built, and running water had not yet been installed. The Sarraut law of 15 March 1928 lead to the quick establishment of vital infrastructure. In 1931 Paray-Vieille-Poste received electricity and water connections, and the work was completed by 1933. The commune was affected by World War II bombings against Orly Airport.
The coat of arms contains bugles of the postilions announcing their passage to tell bystanders to move out of the way, the arms of the Abbey of Saint-Germain-des-Prés, and the arms of Maréchal de Vaux.
