The Cayuga “People of the Great Swamp”) are one of the five original constituents of the Haudenosaunee (Iroquois), a confederacy of Native Americans in New York. The Cayuga homeland lies in the Finger Lakes region along Cayuga Lake, between their league neighbors, the Onondaga to the east and the Seneca to the west. Today, Cayuga people belong to the Six Nations of the Grand River First Nation in Ontario, and the federally recognized Cayuga Nation of New York and the Seneca-Cayuga Tribe of Oklahoma.
