Aigaleo or Egaleo, and known in antiquity as Poikilon Oros, 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. Most of the mountain is rocky (limestone). It is lower than Hymettus. Most of the forest is to its north where the Daphni Monastery is located. There is also a park in its northern reaches.
