The Chitimacha language is a language isolate historically spoken by the Chitimacha people of Louisiana, United States. It went extinct in 1940 with the death of the last fluent speaker, Delphine Ducloux.
Although no longer spoken, it is fairly extensively documented in the early 20th-century work (mostly unpublished) of linguists Morris Swadesh and John R. Swanton. Swadesh in particular wrote a full grammar and dictionary, and collected numerous texts from the last two speakers, although none of this is published.
