Nisa (Ancient Greek: Νῖσος, Νίσα, Νίσαιον;[1][2] Turkmen: Nusaý; also Parthaunisa) was an ancient settlement of the Parthians, located near the Bagyr neighborhood of Ashgabat, Turkmenistan, 18 km west of the city center.

Excavations at Nisa have revealed substantial buildings, mausoleums and shrines, many inscribed documents, and a looted treasury.

Many Hellenistic art works have been uncovered, as well as a large number of ivory rhytons, and rims (coins) decorated with Iranian subjects or classical mythological scenes.
