Gerakas (Greek: Γέρακας) is a town and a former municipality in East Attica, Greece. Since the 2011 local government reform it is part of the municipality Pallini, of which it is the seat and a municipal unit.
In antiquity Gerakas constituted Attica's deme of Gargittos of the Aegides tribe that was located at the mesogea land, according to the administrative model of Cleisthenes. Today, it is a rapidly developing city of the northern mesogea and the eastern gate to the Athens basin. It is known as the birthplace of the famous philosopher Epicurus.
The city is set at a significant place at the junction of Ymittos and Penteli foothills. The limits of Gerakas expand from Stavros up to the Koufos and Desi Hills, 12 km northeast of Athens and just 2 km west of Pallini. The city has a population of 13,990 residents (in 2001), covering a land area of 11 km2 and having a density of 1,265 residents per km2. Gerakas can be seen at an elevation of 190 to 374 metres, giving the area both flat and mountainous characteristics. Due to rapid growth during the last years, Gerakas has a calculated population of 30.000 residents and a density of 2.727 residents per km2, according to municipal estimates.
