Map - Launceston, Tasmania (Launceston)

Launceston or is a city in the north of Tasmania, Australia, at the confluence of the North Esk and South Esk rivers where they become the Tamar River (kanamaluka). As of 2021, Launceston has a population of 87,645. Launceston is the second most populous city in Tasmania after the state capital, Hobart. As of 2020, Launceston is the 18th largest city in Australia. Launceston is fourth-largest inland city and the ninth-largest non-capital city in Australia. Launceston is regarded as the most liveable regional city, and was one of the most popular regional cities to move to in Australia from 2020 to 2021. Launceston was named Australian Town of the Year in 2022.

Settled by Europeans in March 1806, Launceston is one of Australia's oldest cities and it has many historic buildings. Like many places in Australia, it was named after a town in the United Kingdom – in this case, Launceston, Cornwall. Launceston also had the first use of anaesthetic in the Southern Hemisphere, it was the first Australian city to have underground sewers, and it was the first Australian city to be lit by hydroelectricity. The city has a maritime climate with four distinct seasons and is appreciably warmer than the south of the island during summer. Local government is split between the City of Launceston, Meander Valley and West Tamar Councils.

The first inhabitants of the area of Launceston were largely nomadic Aboriginal Tasmanians believed to have been part of the Northern Midlands Tribe.

The first white explorers did not arrive until 1798, when George Bass and Matthew Flinders were sent to explore the possibility that there was a strait between Australia and Van Diemen's Land (now Tasmania). They originally landed in Port Dalrymple (the mouth of the Tamar River), 40 km to the north-west of Launceston.

The first significant colonial settlement in the region dates from 1804, when the commandant of the colonial garrison. Lt. Col. William Paterson, and his men set up a camp on the current site of George Town. A few weeks later, the settlement was moved across the river to York Town, and a year later was moved to its definitive position where Launceston stands.

Initially, the settlement was called Patersonia; however, Paterson later changed the name to Launceston in honour of the New South Wales Governor Captain Philip Gidley King, who was born in Launceston, Cornwall. The name still survives in the tiny hamlet of Patersonia 18 km north-west of Launceston. Paterson himself also served as Lieutenant-Governor of northern Van Diemen's Land from 1804 to 1808.

The geographical area in which Launceston is now located was previously occupied by the Aboriginal Tasmanian Letteremairrener people. The Letteremairrener country encompasses most of the Tamar Valley region. In 1804, reports from early European voyagers describe a number of Letteremairrener camps, consisting of up to ten bark huts located on either side of the Tamar River. Extensive archeological evidence suggests that occupation and usage of the Tamar basin can be dated from at least 7,000 years ago, although it was likely used as long as 35,000 years ago. The Letteremairrener, as seasonal hunter-gatherers, spent the winter months near George Town and the summer months residing on Ben Lomond, before returning to the banks of the Tamar River for the mutton-bird season. Campbell Macknight characterizes early colonial contact with the Letteremairrener people as a mixture of fear, curiosity and aggression. After several aggressive encounters prompted by bands of Letteremairrener in 1806, most likely as revenge for the colonists trespassing and hunting on their land without permission, Colonel William Patterson, in charge of the new settlement in Launceston, led a series of putative skirmishes that were ostensibly continued by colonists until 1831. These conflicts intensified from 1827 until 1831 during the period of the Black War, with genocidal expeditions occurring within the Letteremairrener country and neighbouring areas.

By 1827, Launceston's population had climbed to 2,000 and the town had become an export centre, mainly for the colony's northern pastoral industry. Small hotels and breweries began to emerge in the 1820s before larger, more "substantial" hotels were built in the 1830s. Sporting groups, political groups, churches and schools were often established in these hotels; however, they also hosted plays, musical soirees and readings, until theatres were built.

Ships from Launceston carried parties of sealers to the islands of Bass Strait early in the 19th century. They also took whalers to the coast of Victoria in the 1820s and 1830s where they established temporary bay whaling stations. Some of these temporary communities, such as the ones at Portland Bay and Port Fairy, were the forerunner of permanent settlement of those places. Expeditions from Launceston were involved in the Foundation of Melbourne.

Walter George Arthur, who petitioned Queen Victoria in 1847 while interned with other Aboriginal Tasmanians on Flinders Island, lived for several years in Launceston as one of numerous homeless children, before being taken into custody by George Augustus Robinson who sent him to the Boys' Orphan School in Hobart in 1832.
