Grand Encampment is a town in Carbon County, Wyoming, United States. The population was 443 at the 2000 census.
Known also as "Encampment", this town along the Colorado-Wyoming border was, at the turn of the twentieth century, a booming center of copper mining and smelting. At one point a sixteen-mile tramway was built to carry copper ore from the mountains into the town for smelting. This steam powered tramway was, at the time, the longest in the world. A sharp drop in copper prices and disastrous fires drove the mining company into bankruptcy. Mining operations ceased in the early twentieth century. A large sawmill operated in the town between 1950 and 1998.
