The '''Proastiakos''' ({{langx|el|Προαστιακός}}; "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 station|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 Suburban Railway|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&nbsp;million passengers.<ref>{{cite web|url=http://www.trainose.gr/en/company/|title=Company - TrainOSE|website=www.trainose.gr|access-date=29 May 2020}}</ref>

As of 8 January 2017, the lines between the central stations of Athens and Halkida have been electrified, allowing EMU train service. The lines have been changed, making Athens's central station the main layover station. Those lines are Athens – [[Athens International Airport|ATH]], Athens – [[Kiato]], Athens – [[Chalcis]].

In [[Thessaloniki]], there are two Proastiakos services. The first connects the city's [[Thessaloniki railway station|Main Railway Station]] with the cities of [[Katerini]] and [[Larissa]], and the second links the city with [[Edessa railway station|Edessa]].

In July 2010, a new [[commuter rail]] service was launched in [[Patras]] on a section of the old [[Patras–Kyparissia railway|Patras–Kyparissia line]]<ref name=OSE>{{Cite web|url=http://www.ose.gr/en/o-s-e/network?download=78:network-statement-2017-2-2|title=OSE - 2017 Network Statement Annexes}}</ref> reconnecting the city with [[Rio, Greece|Rio]]. The service was later extended to [[Agios Andreas railway station|Agios Andreas]] as Line P2. In 2020 services were reconnected to [[Kato Achaia railway station|Kato Achaia]]<ref name=OSE>{{Cite web|url=http://www.ose.gr/en/o-s-e/network?download=78:network-statement-2017-2-2|title=OSE - 2017 Network Statement Annexes}}</ref> via [[Agios Andreas railway station|Agios Andreas]] as Line P1.
