Marousi or Maroussi (Greek: Μαρούσι), also known as Amarousio (Αμαρούσιο), is a city and a suburb in the northeastern part of the Athens urban area, 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. Consequently the city's modern name derives from that of the goddess, Amarysia, which denotes the origin of the worship back in Amarynthos, Euboea.
Marousi is situated 13 km (8 mi) northeast of Athens city centre. The municipality has an area of 12.938 km2.
