Aigaleo or Egaleo (Greek: Αιγάλεω), and known in antiquity as Poikilon Oros (Ποικίλον Όρος), is a mountain next to the Athens urban area, in Attica, Greece.

It lies west of the Athens plain, southeast of Eleusis, and east of the island of Salamis.

[1] Towns and places that surround the mountain include Perama, Drapetsona, Nikaia, Korydallos, the highway, and Chaidari.

The Athens Metro connects the area after reducing Iera Odos (Sacred Way) into two lanes in 2002–2003.

The ring presently does not have full access with Athinon Avenue and GR-8 yet, but includes two interchanges.
