Mount Nelson (/maʊntˈnɛlsən/MOWNT-NEL-sən; Nuenonne/palawa kani: kriwalayti) is a mountain and suburb on the southern edge of Hobart, Tasmania, Australia. The mountain rises to a summit elevation of 351 metres (1,152 ft) above sea level and offers sweeping views of the River Derwent, the Meehan Range and surrounding areas.

The suburb covers approximately 5.9 square kilometres (2.3 sq mi), including 14 parklands that account for 16.3% of its area. Its first thoroughfare, Nelson Road, was constructed in 1908 to improve access to the historic Mount Nelson Signal Station, which served as a semaphore link between Hobart and Port Arthur during the colonial era.

Mount Nelson is popular with tourists for attractions such as the Mount Nelson Signal Station, the Truganini Conservation Area, and several walking trails. It also features educational facilities, including Hobart College and the Sustainability Learning Centre, as well as recreational amenities like the University Soccer Club and Mount Nelson Oval. The area's Jurassic dolerite geology supports diverse ecosystems, adding to its historical and ecological significance.

Little is known about the Nuenonne nation, whose territory encompassed Mount Nelson and numerous inner-suburbs of Hobart. The Nuenonne people were profoundly affected by the British colonisation starting in 1803, resulting in a substantial decrease in the Aboriginal Tasmanian population. Colonial official and pastor George Augustus Robinson, accompanied by Aboriginal guide Wurati, gained insights into the indigenous languages and naming conventions of the region during his 1830-31 expedition to the island's northeast. Wurati shared with Robinson various names for places, tribes, and people on the expedition, including the name "kriwalayti" from the Bruny Island language. Robinson documented this term in his manuscripts, associating it with name of Mount Nelson, which can be observed from Bruny Island. The latter part of "kriwalayti" signifies a variation of a southeastern word denoting 'hill', 'mountain', or 'peak', which echoes in other local toponyms. Notably, both the Nuenonne and Muwinina tribes of the Hobart and Sandy Bay areas belonged to the broader southeastern language group, threading cultural and linguistic ties of the region. "kriwalayti" has since been adopted by contemporary Palawa peoples in the reconstructed palawa kani language.

Mount Nelson was named by Governor Macquarie in 1811 after the brig HMS Lady Nelson, which had brought the first colonial fleet to Hobart in 1803. Governor Macquarie himself traveled aboard the same ship during his visit in 1811. Contrary to popular belief, Mount Nelson was not named after the British admiral, Lord Nelson, famous for the Battle of Trafalgar. Instead, Governor Macquarie chose the name to honour the Lady Nelson for its significant role in early Australian exploration and settlement.

Significant suburban development in Mount Nelson commenced post-1945, driven by government initiatives to settle immigrants seeking refuge from the devastation wrought by World War II in Europe. This period witnessed the transformation of Mount Nelson into a thriving residential area. Additionally, the former firing range situated north of the bends on Nelson Road underwent conversion into university farmland for the University of Tasmania.

A Rialannah Post Office opened on 1 April 1948 and was renamed Mount Nelson in 1956. It closed in 1971.

In 1967 a large number of houses were destroyed by the Black Tuesday Bushfires.

A persistent misconception suggests that Mount Nelson was named by Captain Bligh during his 1788 visit aboard the HMS Bounty, in honour of his botanist, David Nelson. However, this claim is inaccurate. The Mount Nelson named by Bligh is actually located on Bruny Island, to the east-southeast of Mount Mangana. The existence of Bligh Court and Christian Street, possibly referencing leader of the mutiny Fletcher Christian, located off Nelson Road, may have further contributed to the perpetuation of this myth. This narrative reflects an instance of whitewashing through "historical distancing," a process by which the past is deliberately separated from the present to lessen the immediacy of historical events and obscure accountability. The enduring story of the HMS Bounty, with its famous mutiny, creates a misleading sense of equivalence or parallel with the Black War and the genocide of the Palawa/Pakana nations, further complicating an honest engagement with Tasmania's colonial history.

Governor Lachlan Macquarie's visit to Van Diemen's Land in 1811 led to the establishment of a signal post atop Mount Nelson. This post served to announce the arrival of ships entering the estuary. The semaphore technology at the signal station became obsolete with the introduction of Tasmania's inaugural telephone line in 1880, linking the Mount Nelson signal station to the Hobart telegraph office. Adjacent to the Signal Station stands the Signal Station Brasserie, housed in the original head signalman’s residence built in 1897.

Historically, signalling operations evolved from flag-based systems to semaphores, with a notable upgrade in 1838 to a towering six-armed semaphore capable of transmitting over 900,000 distinct signals. This network facilitated rapid communication between the penal settlement at Port Arthur and Hobart. Signalmen, often accompanied by their families, endured varying weather conditions, working in shifts from 6am to 9pm.

In 1880, Tasmania's first telephone line replaced the semaphore, marking the advent of modern telecommunications. Despite technological advancements, the station continued to play a crucial role. In 1938 doubts about its future were dispelled.

There was a base station for ship-to-shore radio-telephone communication in 1958. Operations ceased in 1969, ending 158 years of communication history. Since 1979, management of the Mount Nelson site has been under the purview of the Parks and Wildlife Service. Today, the station maintains ties to its heritage, flying the Tasmanian State flag daily and utilising International maritime signal flags to welcome ships and mark special occasions.

Mount Nelson is primarily composed of Jurassic dolerite, a coarse-grained igneous rock that forms much of Tasmania's mountainous terrain. This dolerite originated approximately 165 million years ago during the Jurassic period when extensive volcanic activity led to the intrusion of magma into the Earth's crust. The slow cooling of this magma beneath the surface created the characteristic columnar jointing and durable rock formations seen across the region, including at Mount Nelson.

The dolerite bedrock of Mount Nelson is part of the larger geological structure of the Wellington Range, which also includes nearby peaks like kunanyi / Mount Wellington. Over millions of years, erosion and weathering have shaped Mount Nelson's rounded profile and contributed to the development of nutrient-rich soils on its slopes.

The mountain's geological formations support diverse ecosystems, with variations in soil composition influencing the distribution of native vegetation. Additionally, the exposed dolerite outcrops and slopes provide insight into Tasmania's tectonic and volcanic history.

Mount Nelson’s geology is also notable for its connection to the extensive faulting and uplifting that shaped the broader Derwent estuary and surrounding landscapes. These processes exposed the dolerite intrusions that define the mountain’s rugged terrain today.

Geographically, Mount Nelson is positioned with its short northern boundary abutting the suburb area of Sandy Bay and extending through the University of Tasmania to Churchill Avenue. The northeast boundary follows Lambert Rivulet, traversing through the Skyline and Mount Nelson Signal Station Reserve, while the southern border adjoins the Kingborough Council.

Internally, the suburb of Mount Nelson is bordered by the areas of Fern Tree, Dynnyrne, Ridgeway, and Tolmans Hill, as well as the Southern Outlet. This unique geographic placement offers residents a harmonious blend of urban convenience and natural beauty.
