Merlynston railway station is a commuter railway station on the Upfield line, part of the Melbourne railway network. It serves the northern suburb of Coburg North in Melbourne, Victoria, Australia. Merlynston station is a ground-level unstaffed station, featuring an island platform. It opened on 8 October 1889, with the current station provided in 1959. It initially closed on 13 July 1903, then reopened on 1 October 1914.

Initially opened as North Coburg, the station was given its current name of Merlynston on 6 February 1922.

Merlynston station opened when the railway line was extended from Coburg to Somerton. The locality was named by Donald Bain who, in 1919, purchased 31 hectares of land to be subdivided into a housing estate. Bain named the estate after his daughter, Merlyn.

In 1948, flashing light signals were provided at the Boundary Road level crossing, in the down direction from the station. In 1959, the current island platform was provided when the line was duplicated between Coburg and Fawkner.

In 1984, boom barriers were provided at the Boundary Road level crossing.

In November 1998, the level crossing at Shorts Road, south of the station, was closed, and a dead-end street was created on either side of the railway line. Until the track was duplicated to Gowrie in that year, the line north of the station had only a single track, apart from the island platform at Gowrie, which had two platforms. However, one of those was a dock platform, meaning trains couldn't pass each other at Gowrie, and had to do so at Merlynston.

On 9 April 2002, Comeng motor carriage 533M was destroyed by a fire at the station. The fire also damaged part of the station building.
