Châtillon (French pronunciation: ​[ʃɑ.ti.jɔ̃]) is a commune in the southwestern suburbs of Paris, France. It is located 7 km (4.3 mi) from the center of Paris.

The town was formerly named Châtillon-sous-Bagneux, and a relic of this denomination remains in at least one road sign in Vanves (located at the junction Boulevard du Lycée and Avenue Charles de Gaulle, and written as Châtillon s/ B).

The TGV trains are maintained at the "Établissement Industriel de Maintenance du TGV de Châtillon" (EIM TGV de Châtillon).

Châtillon is served by Châtillon – Montrouge station on Paris Métro Line 13.

Châtillon enjoys a well connected bus service: from Paris, the 68 comes all the way from the Place de Clichy to the metro station. Buses 194, 195 and 295 all leave Porte d'Orléans and pass by the Châtillon – Montrouge metro station from where they continue mostly in different directions. The 162 running east and west of Châtillon can take you to the RER station in Meudon, or the shopping centre to the east. The 394 which passes by the market is ideal for Clamart, Vanves, and Issy-les-Moulineaux. If you need to get to Issy from the metro, then take the 126.

The name of the town is first documented in 1192 in the archives of St-Martin-des-Champs Priory in Medieval Latin as "Castellio" ("little castle"). It is not known where this castle was located. Two possible locations are the heights of Châtillon (to the southwest) or in the former market town on the manor. This manor was owned by the Abbey of Saint-Germain-des-Prés until 1600, when it was sold to Richard Tardieu. The small town grew slowly. During the 14th century a chapel dedicated to a Saint Eutropius was built and a parish established. In addition to agriculture, the exploitation of a rock quarry provided an economic basis for the town.
