Hadspen is a town on the South Esk River in the north of Tasmania, Australia, 8 kilometres (5.0 mi) south west of Launceston. Hadspen has few commercial establishments and is primarily a residential suburb of nearby Launceston. Most of the town's buildings are residential, and relatively recent. The town's population of just over 2000 has grown rapidly from only a few hundred in the 1960s, and there are development plans that call for its doubling.

Settlement began in the early 19th century as a cluster of houses on the Launceston side of the river, near a frequently-flooded ford. Over time various bridges were built, largely on the same site, across the river. Though it had been settled for some time, Hadspen was officially declared in 1866. Hadspen was originally on the main road from Launceston to Devonport, but the town's centre was bypassed in the late 20th century. There have been schools, both secular and religious, in its history, though none now remain.

The town has heritage-listed properties and few others from colonial times. The town's historic centrepiece is Entally House, built in 1819 as a wealthy settler's colonial estate. It was the former family home of Thomas Reibey, Premier of Tasmania from 1876 to 1877. The Red Feather Inn was built in the 1840s and is currently used for accommodation and also has an on-site restaurant. The Tasmanian Walking Company use the inn as their northern walker base. A gaol from the same time reflects Tasmania's convict past. The Uniting Church building dates back over 150 years, originally as a Wesleyan chapel, and the Anglican Church of the Good Shepherd is known for taking over ninety years to complete.

Hadspen lies approximately 142 metres (466 ft) above sea level, 8 kilometres (5.0 mi) Southwest of Launceston, Tasmania. It is on the southern side of the South Esk River, near the confluence of the South Esk and Meander Rivers. The town is set in a rural landscape; Surrounding countryside contains valleys, river flood plains, remnant uncleared bush and undulating pastures. The majority of the town lies between the South Esk, and a low section of land east of the town called Beams Hollow, which is named after Thomas Beams, owner of a 50 acres (20 ha) lot through which the road from Launceston first ran.

As of 1831, there was a settlement named Hadspen near a ford of the South Esk River. A road was proposed from Launceston, crossing the river at this ford near Thomas Haydock Reibey's property of Entally. The name may have been given by surveyor George Frankland after Hadspen house and garden, an estate in Somerset, England. By the 1840s Hadspen was a small cluster of houses near "Reibey's ford", and the river crossing was now on the main road from Launceston. Hadspen Post Office opened on 1 November 1849, though the town was not declared in the government gazette until January 1866. A bridge was constructed in the early 1840s replacing the often impassable ford, and during the next century the bridge was often repaired and sometimes replaced.

Hadspen.-This rural township, long marked out on the maps, is fast assuming the appearance of a village. It is situated close to and on this side of Reibey's Bridge. Mr. Sprunt lately obtained a licence to open an inn, which is a large and commodious brick building. Several cottages are erected, and a blacksmith's forge for the convenience of surrounding settlers will soon be at work. Abundance of excellent stone is found within a few yards of the spot, and we observe one gentleman has built a remarkably neat cottage, fronting the main street, of this material. The distance from Launceston is about eight miles, and if the road were slightly repaired the drive in this direction would be the most pleasant in the neighbourhood

In early years there were two Hotels: Cricket Club Hotel near the river, which was partly destroyed by flood in the 1870s and subsequently demolished, and Hadspen Hotel, a convict-built sandstone structure. By 1881 both had closed and there were no hotels in the town. An application to re-licence a building opposite the Wesleyan church was unsuccessful. The Hadspen Hotel was a private home in the early 20th century and remains as part of the town's heritage. None of these hotels are open in the 21st century, the Rutherglen complex on the town's west is the only licensed premises. There was a brewery in the town for a time, though it has long closed. The postal service from Hadspen originally was handled by a licensee operating from a shop, and subsequently from one of hotels. By 1966 the post office was in a separate building on the site of the former blacksmith's shop.
