Choisy-le-Roi (46,122 inhabitants, 543 ha) is a commune in the Val-de-Marne department.

Choisy is said to have first appeared in history when Caesar's army, led by the commander Labienus, fought a battle in what is now the commune. Its name comes from Sociacum, meaning "villa of Soisus" or "Socius."
Choisy has only been known since 1176, as part of the seigneury of Thiais, which belonged to the Abbey of Saint-Germain-des-Prés. In 1207, with the consent of the Bishop of Paris, John, Abbot of Saint-Germain-des-Prés, gave the inhabitants of Choisy a plot of land to build a chapel dedicated to Saint Nicholas. In 1224, the building was established as a parish church.

In 1678, Anne-Marie-Louise d'Orléans, Duchess of Montpensier, purchased a house and, in 1682, had a château built in Choisy, with architecture by Jacques Gabriel and exterior sculptures by Étienne Le Hongre. Choisy then became Choisy-Mademoiselle. She had the church choir rebuilt and the nave repaired. In 1693, the Grand Dauphin, son of Louis XIV, inherited this land, which he exchanged with Madame de Louvois for the seigneury and the Château de Meudon. The château then belonged to the Dowager Princess of Conti, the legitimated daughter of Louis XIV and the Duchess of La Vallière. In 1739, upon the princess's death, Louis XV acquired the château to create a residence near the Sénart forest, where he would hunt. He decided that the village would henceforth be named Choisy-le-Roi. The parish greatly benefited from the king's presence, as he enlarged the old château and added new buildings. Madame de Pompadour moved in in 1746, where festivals became increasingly popular. From 1775 to 1780, Marie-Antoinette organized all kinds of entertainment there. The population had grown throughout the 18th century.

The Revolution was as intense in Choisy as it was in Paris, with the town's mayor maintaining close ties with Robespierre. Choisy-le-Roi bore the revolutionary name of Choisy-sur-Seine, and the royal estate, of which only the entrance remains today, was sold as national property and slowly fell into disrepair.
From 1809, the Navier Bridge replaced the ferry. In the 19th century, Choisy-le-Roi experienced an industrial boom with the establishment of the Boulenger earthenware factory, the tile factory, and the crystal factory. 1840 saw the arrival of the train in Choisy-le-Roi with the inauguration of the Paris-Corbeil line, which would mark the beginning of the Paris-Orléans line. The town suffered extensive damage during the Franco-Prussian fighting in an attempt to liberate Paris on September 30, 1870.
The expanding municipality purchased Mr. Lagoutte's house in 1903, built under Napoleon III in the former forecourt of the château. The rest of the park was subdivided, with the construction of schools in 1910.
The Choisy Bridge was rebuilt from 1962 to 1965 based on a design by Jean Muller, using a new technology: the precast concrete deck with segmented caissons.

From 1968 to 1973, Choisy-le-Roi hosted the Vietnamese delegation for the Paris negotiations, originally scheduled for four months, in the building on Avenue de Versailles, which was at that time the headquarters of the central school of the French Communist Party and the former residence of Maurice Thorez and Jeannette Vermeersch.
