Portlethen railway station serves the town of Portlethen in Aberdeenshire, Scotland. It is sited 232 miles 59 chains (374.6 km) from Carlisle via Perth, and is between Stonehaven and Aberdeen, on the Dundee to Aberdeen line.

The station was opened on 1 February 1850. After closure on 11 June 1956, the station was reopened nearly 30 years later on 17 May 1985.

In 2021, an investigation was started after trains went through an emergency speed restriction near the station close to line speed.

Unstaffed, the facilities at the station are minimal, consisting of two car parks (and sets of bike racks), and shelters and benches on each platform. There is, however, step-free access to and between the platforms (the latter via Cookston Road). There is a ticket machine in shelter on platform 2.

The statistics cover twelve month periods that start in April.

Portlethen previously had a somewhat limited service, with trains only calling early in the morning and evening peaks and at night times with large gaps at certain times during the day, but an improved timetable has accounted for much of the growth in recent years. As of May 2026, there is approximately one train per hour in each direction between Montrose and Inverurie.
