Kiato railway station (Greek: Σιδηροδρομικός Σταθμός Κιάτου, romanized: Sidirodromikós Stathmós Kiátou) is a station in Kiato in the northern Peloponnese, Greece. The station is located 1 km west of the town, near the A8 motorway between Athens and Patras. It was opened on 9 July 2007. The station is served by the Athens Suburban Railway towards Piraeus and Hellenic Train local services to Aigio. It should not be confused with the now-closed station on the old Piraeus–Patras railway, which is located northeast of the current station, closer to the coast of the Corinthian Gulf.

It opened on 9 July 2007 as the western terminus of the new standard-gauge line from Athens Airport. In 2009, with the Greek debt crisis unfolding OSE's Management was forced to reduce services across the network. Timetables were cutback and routes closed, as the government-run entity attempted to reduce overheads. Initially, Kiato railway station served as an exchange point for passengers to Patras on the old metre-gauge line from Piraeus, but all regional services on the metre-gauge lines of the Peloponnese were suspended indefinitely in December 2010 for cost reasons. The old Kiato–Sikyona railway station [el] nearby was also closed. In 2017 OSE's passenger transport sector was privatised as TrainOSE, currently a wholly owned subsidiary of Ferrovie dello Stato Italiane infrastructure, including stations, remained under the control of OSE. In July 2022, the station began being served by Hellenic Train, the rebranded TranOSE.

In August 2025, the Greek Ministry of Infrastructure and Transport confirmed the creation of a new body, Greek Railways (Greek: Σιδηρόδρομοι Ελλάδος, romanized: Ellinikí Sidiródromi Monoprósopi) to assume responsibility for rail infrastructure, planning, modernisation projects, and rolling stock across Greece. Previously, these functions were divided among several state-owned entities: OSE, which managed infrastructure; ERGOSÉ, responsible for modernisation projects; and GAIAOSÉ, which owned stations, buildings, and rolling stock. OSE had overseen both infrastructure and operations until its vertical separation in 2005. Rail safety has been identified as a key priority. The merger follows the July approval of a Parliamentary Bill to restructure the national railway system, a direct response to the Tempi accident of February 2023, in which 43 people died after a head-on collision.

The raised station is assessed via stairs or a ramp. It has one side platform and one island platform, with station buildings located on platform 1, with access to the platform level via stairs or lifts. The Station buildings are equipped with a booking office, and toilets. At platform level, there are sheltered seating, an air-conditioned indoor passenger shelter (as of 2020 not open) and Dot-matrix display departure and arrival screens (inoperable as of 2019) and timetable poster boards on both platforms. This is a small shop and a café on the ground level, just next to the entrance overlooking the carpark. There is a large car park on-site, adjacent to the eastbound line. As of 2025, there is no local bus stop connecting the station.

Since 15 May 2022, this station serves the following routes:

Pending the electrification of the Kiato–Aigio section, passengers must change between electric and diesel trains at Kiato. Those travelling to and from the airport may also take lines 1 and 2, changing trains at Kato Acharnai. Pending the completion of the Athens Airport–Patras railway, passengers travelling to and from Patras may use Hellenic Train's rail replacement bus services (ten per-day, as of 2025), which connect the city with Kiato, Diakopto and Aigio stations. Diakopto is also the terminus of the unique rack railway to Kalavryta.
