Tlingit (English: /ˈklɪŋkɪt/ KLING-kit; Lingít Tlingit pronunciation: [ɬɪ̀nkɪ́tʰ]) is an endangered language indigenous to Southeast Alaska and Western Canada spoken by the Tlingit people that forms an independent branch of the Na-Dene language family. Although the number of speakers is declining, extensive effort is being put into revitalization programs in Southeast Alaska to revive and preserve the language.
Missionaries of the Russian Orthodox Church were the first to develop a written version of Tlingit by using the Cyrillic script. After the Alaska Purchase, Tlingit language use was suppressed by the United States government, though preservation programs were introduced beginning in the 20th century. Today, Tlingit is spoken natively by perhaps only 100 elders.
