Marousi or Maroussi (Greek: Μαρούσι, also Αμαρούσιο Amarousio) is a suburb in the northeastern part of the Athens agglomeration, Greece. Marousi dates back to the era of the ancient Athenian Republic; its ancient name was Athmonon (Ἄθμονον) and it represented one of the 10 Athenian sub-cities. The area held a main ancient temple, where Amarysia Artemis, the goddess of hunting, was adored, and the city's modern name derives from that of the goddess, Amarysia, which denotes the origin of the worship back in Amarynthos, Euboea.
