Houilles (French pronunciation: [uj] ^ⓘ) is a commune in the Yvelines department in the Île-de-France region in north-central France. It is a northwestern suburb of Paris, located 14.2 km (8.8 mi) from the center of Paris.

Until 2000, the command post of the French Navy's Ballistic Missile Submarine Force was based at Houilles.

Victor Schœlcher, a French abolitionist writer in the 19th century and the main spokesman for a group from Paris who worked for the abolition of slavery died in Houilles on 25 December 1893. A nursery school, a street and a statue carry his name. The house in which he died in 1893 is at 26 Avenue Schœlcher. The commune of Houilles acquired the house in 2011.
