The population was 869 at the 2010 census.[1] It is the northernmost town in New Hampshire and the largest town by area in the state – and in New England as well – more than twice the size of the next largest town, Lincoln. U.S. Route 3 is the only major highway in the town, although the northern terminus of New Hampshire Route 145 also lies within Pittsburg. Pittsburg derives its name from , Prime Minister of the United Kingdom. Prior to its incorporation in 1840, the area was settled ca 1810 and known as the Territory of Indian Stream. It had the unique distinction of having been its own microstate briefly during the 1830s, called the Republic of Indian Stream, due to an ambiguous boundary between the United States and Canada. Pittsburg is the northernmost New Hampshire municipality. It shares an international border with Québec province, Canadato its west and north, and borders the states of Maine (to the east) and Vermont (a very small portion to the southwest). Directly to the south is Clarksville. Pittsburg is the only New Hampshire municipality to border Canada, the only one that borders both Maine and Vermont, and the only one to share a land border with Vermont. Pittsburg contains the only part of New Hampshire west of the Connecticut River, as that river defines the Vermont state line from Clarksville southward. New Hampshire's only Canadian border crossing is located at the northern end of town at the terminus of U.S. Route 3. The western edge of Pittsburg is defined by Halls Stream, being the "northwesternmost headwaters of the Connecticut River", which defined (ambiguously) the border in the Treaty of Paris of 1783. Contained within the boundaries of Pittsburg are the Connecticut Lakes, which form the beginning of the Connecticut River. Pittsburg also contains the communities of Happy Corner, Idlewilde, and The Glen. Early maps (e.g. 1854) also show several grants that were incorporated into the eastern edge of Pittsburg, including Carlisle No. 1, Webster/Carlisle No. 2 and Hubbards No. 3, all north of Atkinson and Gilmanton Academy Grant. According to the United States Census Bureau, the town has a total area of 291.2 square miles (754 km2), the largest of any municipality incorporated as a town in New England. 281.4 square miles (729 km2) of it is land and 9.8 square miles (25 km2) of it is water, comprising 3.37% of the town.[2] The highest point in Pittsburg is the summit of Stub Hill, at 3,627 feet (1,106 m) above sea level.
