Semley was a railway station in Wiltshire, England. It was served by trains on the West of England Main Line and was the railhead for the town of Shaftesbury, Dorset, 2.5 miles (4.0 km) to the south. Although several plans were made to give Shaftesbury its own station, the town's position on a hill prevented this. The nearest station to Shaftesbury is now Gillingham.
