Kauklahti railway station (Finnish: Kauklahden rautatieasema, Swedish: Köklax järnvägstation) is a station on the Helsinki commuter rail network located in Espoo, Finland.

The Finnish Heritage Agency has classified Kauklahti railway station as a nationally significant built cultural environment.

[2][3] During the planning of the Rantarata railway line Kauklahti was regarded as the best location for a railway station by the residents of Espoo, since it was located near the Espoo Manor and the densely populated rural region near the manor.

When Finnish long-distance trains were allowed to pass through the naval base starting from 1947, the windows on the train carriages were covered and the Finnish locomotive was changed to a Soviet locomotive at the Kauklahti station.

[3] When Porkkala was returned to Finland in 1956, the significance of the Kauklahti station decreased.
