Aspropyrgos (Greek: Ασπρόπυργος) is a suburb of Athens.
The Aspropyrgos Refinery, south of the city, has been producing oil for many years. It is the largest in Greece, with an annual capacity of 135,000 bbl/d (21,500 m3/d). As a consequence, pollution has been a problem for years. The refinery includes depots in the southern and eastern parts, and some in the western part and at a dock to the southwest.
