Na-Dené (also Na-Dene, Naene, Athabaskan-Eyak-Tlingit) is a proposed Native American language family which includes the Athabaskan languages, Eyak, Tlingit, and possibly Haida. The connection of Haida to the other languages is controversial. In February 2008 a proposal relating Na-Dene to the Yeniseian language Ket, spoken in Siberia, has been published and well received by a number of linguists.
