The Proastiakos (; "suburban") is Greece's commuter rail service, run by Hellenic Train, on rail infrastructure owned by the Hellenic Railways Organisation (OSE) (lines) and GAIAOSE (buildings and Trains). These services connect a participating city's central railway station to important locations such as a city's port or airport, as well as its suburbs and occasionally nearby towns and cities.
As of September 2020, there are three Proastiakos networks serving the country's three largest cities: Athens, Thessaloniki, and Patras, providing them with commuter rail links towards their suburbs and also with regional services to other cities and towns. In 2016, the three systems carried 10.1 million passengers.
