Portesham was a small railway station serving the village of Portesham in the west of the English county of Dorset.
The station was sited across the fields from village not far from an underbridge carrying the line across the Weymouth to Abbotsbury road at a skew angle. Just to the east of the station an incline provided access to quarries near the Hardy Monument.
The station was opened on 9 November 1885 by the Abbotsbury Railway when it opened the line from to on the Great Western Railway (GWR) (former Wilts, Somerset and Weymouth Railway line).
The station had a single platform and a passing loop. The goods shed was opposite the platform and functioned for the life of the branch.[1] The station was the site of a GWR camp coach from 1935 to 1939.
The station closed with the branch on 1 December 1952.

The station building is now part of a private dwelling and is used as a holiday let.
