Goiogouen (also spelled Gayagaanhe and known as Cayuga Castle), was a major village of the Cayuga nation of Iroquois Indians in west-central New York State. It was located on the eastern shore of Cayuga Lake on the north side of the Great Gully Brook, about 10 miles (16 km) south of the large 17th-century Cayuga town of Tiohero; and approximately along the southern line of the modern-day township of Springport, New York.
