Tacanan is a family of languages spoken in Bolivia, with Ese’ejja also spoken in Peru. It may be related to the Panoan languages. Many of the languages are endangered.
Toromono may be extinct. Another possibly extinct Tacanan language is Mabenaro; Arasa has been classified as Tacanan, but appears to have more in common with Panoan.
