Angoon (sometimes formerly spelled Angun) (Tlingit: Aangoon) is a city on Admiralty Island in Hoonah-Angoon Census Area, Alaska, United States. At the 2000 census the population was 572, by the 2010 census the population had declined to 459. The name in Tlingit, Aangóon, means roughly "isthmus town."
Admiralty Island has long been the home of the Kootznoowoo Tlingit group, or Xootsnoowú Ḵwáan in Tlingit. Kootznoowoo means "fortress of brown bears", literally xoots-noow-ú "brown.bear-fortress-possessive". Angoon has a less-rainy climate than most of southeastern Alaska and was valued by the Tlingit for that reason.
During the Russian period in Alaska, from the 18th century to the mid-19th century, fur trading was a major economic activity in the area.
In 1878, after the 1867 Alaska Purchase, the Northwest Trading Company established a trading post and whaling station on nearby Killisnoo Island and employed Angoon villagers to hunt whales. Whaling, a school and a Russian Orthodox Church attracted many Tlingits to neighboring Killisnoo.
In 1882, a whaling vessel's harpoon charge accidentally misfired and exploded, killing a crewmember who was a Tlingit shaman, or medicine man. Villagers demanded payment of 200 blankets to the man's family, as was customary. The Northwest Trading Company sought help from the United States Navy at Sitka. Angoon and a nearby summer camp were shelled and destroyed by the revenue cutter .
After a short time, the Northwest Trading Company switched to herring processing. During this time, many Tlingits moved to Killisnoo for employment at the fish plant. In 1928, Killisnoo was destroyed by fire and many Tlingits returned to Angoon.
In 1973, Angoon won a U.S. $90,000 settlement from the United States government for the 1882 bombardment.
