Coubron (5,156 inhabitants, 414 ha) is the less populated commune in the Seine-Saint-Denis department, in the eastern suburbs of Paris.

In the 5th century, settlers established themselves on the site of Coubron and named it Curtis Bréonis, the land or estate of Bréon, a term of Germanic origin meaning "broad" or "strong." Around 1180, Robert II de Mauvoisin, son of Raoult IV de Mauvoisin, from a bourgeois family of Paris, was the lord of the lands of Coubron and Villemomble.
In 1317, Pierre de Chambly inherited the property. It was therefore at the very beginning of the 14th century that the lands of Coubron and Aulnay were annexed to those of Livry. Until the end of the 16th century, the village was part of the parish of Livry.

In the 18th century, Jean Hyacinthe Hocquart de Montfermeil was the Marquis of Montfermeil and Lord of Coubron. He died in 1764. His grandson, Jean-Hyacinthe Louis Hocquart de Montfermeil, the last Marquis of Montfermeil (1752-1798), was also the last Lord of Coubron.
Between 1867 and 1875, Jean-Baptiste Camille Corot frequently stayed in the village and set up a studio there, which no longer exists.

The Vaujours fort, located primarily in the commune of Courtry (Seine-et-Marne) and partly in Coubron, was used by the French Atomic Energy Commission (CEA) to test detonators for French atomic bombs
from 1951 to 1997, leaving behind significant radioactive pollution, measured in 2001 and 2011 by CRIIRAD.

Flag of Coubron

The arms of Coubron are blazoned :
Or, 3 hunting horns sable stringed azure, on a chief gules 3 roses argent.
The three hunting horns were the emblem of the Nesmond family, owners of the commune in the 17th century. These horns are combined with the three roses of the Hocquart family, owners from 1741, and created
marquises in 1778, until the French Revolution.

The flag is white with the coat of arms, and the name of the commune and of the department below: photo (2025).
