Seneca (in Seneca, Onödowá'ga:' or Onötowá'ka:') is the language of the Seneca people, one of the Six Nations of the Iroquois League. About 10,000 Seneca live in the United States and Canada, primarily on reservations in western New York, with others living in Oklahoma and near Brantford, Ontario. As of 2013, an active language revitalization program is underway.
