Alfortville (French pronunciation: [alfɔʁvil] ⓘ) is a commune in the Val-de-Marne department in the southeastern suburbs of Paris, France.

Alfortville is served by two stations on Paris RER D: Maisons-Alfort–Alfortville and Le Vert de Maisons.

Alfortville is located at only 500 meters from the metro station École Vétérinaire de Maisons-Alfort on Paris Métro Line 8.

There are streets named after Komitas Vartabed, Missak Manouchian, and the city of Yerevan.

After military clashes in the Armenian-populated breakaway Nagorno-Karabakh region between Armenian and Azerbaijani troops resumed in 2020, the city council of Alfortville unanimously voted to support the recognition of its independence under its Armenian name of Artsakh Republic,[5] making it the first French city to do so.
