Tututni (Dotodəni, alternatively "Tutudin"), also known as Coquille and (Lower) Rogue River, is an extinct Athabaskan language once spoken by three Tututni (Lower Rogue River Athabaskan) tribes: Tututni tribe (including Euchre Creek band), Coquille tribe, and Chasta Costa tribe who are part of the Rogue River Indian peoples of southwestern Oregon. Ten speakers remained in 1961; the last fluent speaker died in 1983. In 2006 students at Linfield College participated in a project to "revitalize the language."  It is one of the four languages belonging to the Oregon Athabaskan cluster of the Pacific Coast Athabaskan languages.
Dialects were Coquille (Upper Coquille, Mishikhwutmetunee), spoken along the upper Coquille River; Tututni (Tututunne, Naltunnetunne, Mikonotunne, Kwatami, Chemetunne, Chetleshin, Khwaishtunnetunnne); Euchre Creek, and Chasta Costa (Illinois River, Šista Qʼʷə́sta).
