Wichita is an extinct Caddoan language once spoken in Oklahoma by the Wichita and Affiliated Tribes. The last fluent heritage speaker, Doris Lamar-McLemore, died in 2016, although in 2007 there were three first-language speakers alive. This has rendered Wichita functionally extinct; however, the tribe offers classes to revitalize the language and works in partnership with Wichita Documentation Project of the University of Colorado, Boulder.
