The Tlingit (ˈtlɪŋkɪt,_ˈklɪŋkɪt ; also spelled Tlinkit) are indigenous peoples of the Pacific Northwest Coast of North America. Their language is the Tlingit language (natively Lingít, pronounced ɬɪ̀nkɪ́th), in which the name means 'People of the Tides'. The Russian name Koloshi (Колоши, from a Sugpiaq-Alutiiq term kulut'ruaq for the labret worn by women) or the related German name Koulischen may be encountered referring to the people in older historical literature, such as Grigory Shelikhov's 1796 map of Russian America.
The Tlingit have a matrilineal kinship system, with children considered born into the mother's clan, and property and hereditary roles passing through the mother's line. Their culture and society developed in the temperate rainforest of the southeast Alaskan coast and the Alexander Archipelago. The Tlingit maintained a complex hunter-gatherer culture based on semi-sedentary management of fisheries. Hereditary slavery was practiced extensively until it was outlawed by the United States. An inland group, known as the Inland Tlingit, inhabits the far northwestern part of the province of British Columbia and the southern Yukon in Canada.
The greatest territory historically occupied by the Tlingit extended from the Portland Canal along the present border between Alaska and British Columbia, north to the coast just southeast of the Copper River delta in Alaska. The Tlingit occupied almost all of the Alexander Archipelago, except the southernmost end of Prince of Wales Island and its surroundings, where the Kaigani Haida moved just before the first encounters with European explorers.
The Coastal Tlingit tribes controlled one of the mountain passes into the Yukon interior; they were divided into three tribes: the Chilkat Tlingit (Jilḵáat Ḵwáan) along the Chilkat River and on Chilkat Peninsula, the Chilkoot Tlingit (Jilḵoot Ḵwáan) and the Taku Tlingit (Tʼaaḵu Ḵwáan:) along the Taku River.
Inland, the Tlingit occupied areas along the major rivers that pierce the Coast Mountains and Saint Elias Mountains and flow into the Pacific, including the Alsek, Tatshenshini, Chilkat, Taku, and Stikine rivers.
