Melcombe Regis was a station on the Portland Branch Railway in the west of the English county of Dorset. Opened in April 1909, it was sited at the north end of the bridge over Radipole Lake. The station was built to enable Portland branch passengers to go to Weymouth without the need for the branch train to reverse to enter Weymouth railway station. The branch junction was to the north of Weymouth station and faced Dorchester. The station closed officially with the branch on 3 March 1952. However the station continued to be used for overflow from the adjacent Weymouth station. particularly on summer Saturdays, regularly until 12 September 1959, and irregularly for a while after that.
Operated by the Great Western Railway, it was placed in the Western Region when the railways were nationalised in 1948.
Goods trains continued to pass the site on their way to the Admiralty sites on Portland until 1965.
The site was near a car park at the north end of the relief road bridge that replaced the old girder bridge over the backwater. For a long time there was a Go-Kart track next to the remains of the platform, which was overgrown. The site has since been developed as Jubilee Business Park.
