Koasati or Coushatta is a Muskogean language spoken in Allen Parish, north of Elton in Louisiana, and near Livingston in Texas. The exact number of speakers is uncertain, but officials of the Coushatta tribe believe that the majority of tribal members over 20 speak Koasati.
In 2007 a program to revitalize the Koasati language was started by the Coushatta Tribe of Louisiana in collaboration with McNeese State University in Louisiana and the College of William and Mary in Virginia.
The closest languages to Koasati are Mikasuki and Alabama, and there is apparently considerable mutually intelligibility between Koasati and Mikasuki, though not with Alabama.
