Pomathorn Halt railway station served the town of Penicuik, Midlothian, Scotland from 1855 to 1962 on the Peebles Railway.

The station opened on 4 July 1855 by the Peebles Railway. The station was situated on the north side of the B6372. The station was originally called Penicuik, but it was renamed Pomathorn on 2 December 1872, although the station signs always called it 'Pomathorn for Penicuik'. The goods yard was accessed from the north and consisted of three sidings, two of which served a cattle dock. The station was downgraded to an unstaffed halt on 1 November 1946 and the suffix 'halt' was added to its name on 7 July 1947, although it didn't appear on tickets or signs, just the timetables.

Following the closure of Penicuik station in September 1951 - terminus of the Penicuik railway, half a mile nearer the centre of town - Pomarthorn became Penicuik's only station. It closed to passengers and goods traffic on 5 February 1962.
