Kanadaseaga, was a major village, perhaps a capital, of the Seneca nation of the Iroquois Confederacy in west-central New York State, United States. It was located between the northern ends of Seneca and Canandaigua lakes, one and a half miles northwest of the present-day city of Geneva in the township of Seneca. The village was situated on both sides of Kanadaseaga Creek. The Seneca established this village at least as early as 1687. It was likely established by the former residents of Ganondagan, after its destruction by the French.
