Montmorency (French pronunciation: [mɔ̃mɔʁɑ̃si] ⓘ) is a commune in the Val-d'Oise department, in the northern suburbs of Paris, France.

Maurentiacus, the name of the area surrounding the promontory, meant "estate of Maurentius", probably a Gallo-Roman landowner.

Three years later in 1793, at the peak of the French Revolution, the name of the commune, which was probably thought of as too reminiscent of the overthrown Ancien Régime, was changed into Émile, in honor of French philosopher and writer Jean-Jacques Rousseau who had composed his educational treaty Émile a few decades earlier while in residence at Montmorency.

The art collector Pierre Crozat had a country retreat here in the first half of the 18th century, the fashionable Château de Montmorency, which was at the centre of social gatherings.

It contained a chapel decorated in 1715-16 by Pierre Le Gros the Younger[3] and paintings by Charles de La Fosse.

This station is located in the neighboring commune of Enghien-les-Bains, 2.1 km (1.3 mi) from the town center of Montmorency.
