The Hellenic Electric Railways (Greek: Ελληνικοί Ηλεκτρικοί Σιδηρόδρομοι, romanized: Ellinikoi Ilektrikoi Sidirodromoi, ΕΗΣ) was a private owned company member of British company "Power and Traction Company Ltd" which operated and extended the present Line 1 of the Athens Metro, from 14 April 1926 to 31 December 1975.

The company was nationalised and replaced by the Athens–Piraeus Electric Railways, on 1 January 1976: that company was later absorbed by STASY on 17 June 2011.
