It was opened on 8 August 1864 by the Pembroke and Tenby Railway as an extension of their route from to serve the Royal Navy dockyard in the town, though it was not until 1866 that the P&T route finally reached the main line at Whitland. The line was notable when constructed as it was built as standard gauge, not the 7-foot broad gauge used by the Great Western Railway at the time; and so it was isolated from the South Wales Railway main line until 1868, when dual gauge track was laid as far as to meet the standard gauge tracks of the London and North Western Railway. In 1872, the GWR converted all of its lines in the area to standard gauge. Originally, the station had two platforms. Both remain but only the southern one is in use. Part of the main building has been converted into The Station Inn, a real alepub. Originally carrying munitions, the freight branch ran past the station across local streets down to the actual dockside until 1969. Subsequently, albeit partially, the track has been lifted.

Trains run every two hours Mon-Sat, with a less frequent service on Sundays. On summer Saturdays, the station is also used by Great Western Railway who provided two InterCity 125s in each direction: two to London Paddington, one from London Paddington and one early morning HST starting its journey from Swansea. One through train in each direction is named the Pembroke Coast Express. For the 2019 summer season, the new Class 800 train sets have replaced the HST sets formerly used.
