Hagley is a rural locality and town in the local government area of Meander Valley in the Launceston region of Tasmania. The locality is about 5 kilometres (3.1 mi) north-east of the town of Westbury. The 2016 census has a population of 335 for the state suburb of Hagley.

A rail line near Hagley was first surveyed in 1856, as part of a route from Launceston to Deloraine. A decade later a Railway Act was passed, strongly supported by then Premier of Tasmania Sir Richard Dry. A private company, the Launceston and Western Railway Company, was formed to build the route and the first sod turned in January 1868 by Prince Alfred, Duke of Edinburgh. The rail line passed 0.5 miles (0.8 km) south of the town and a station was built 2 miles (3 km) distant. The line opened, and the first train passed near Hagley, on 10 February 1871. The rail line carried passengers, and several daily mail deliveries. Launceston and Western Railway soon ran into financial problems, the line closed 29 June 1872 and the company itself went bankrupt on 25 July. The government took over the railway, as the Tasmanian Government Railways, on 31 October 1873. Local farmers petitioned for an additional line to properties in Hagley’s west. Construction began on the new line in 1887 and a siding as built at the intersection of Hoggs Lane. This siding was used first for farm produce, later facilities for loading stock were added. A platform and waiting room were added in 1910, though it was some years before passenger trains stopped at Hoggs Lane. The passenger rail service had stopped before 1978, a time when all Tasmanian passenger rail services ceased.
