Petralona (Greek: Πετράλωνα, pronounced [peˈtɾa.lo.na]) is a neighborhood of the center of Athens, Greece.

Sometimes as part of Ano Petralona refers and the small neighbourhood Assyrmatos.

Petralona is named after the Greek words 'Petrina Alonia' (πέτρινα αλώνια) which means 'stone threshing floors', which were used in the area to thresh grain before urbanisation.

Goats were banned from the city of Athens in February 1925 and from that point on, the area has held its current name.

The district is served by the Petralona Station on Line 1 of the Athens Metro and it's also not that far from the Metro Station (Line 3) Kerameikos.
