Canandaigua (Utaʼnaráhkhwaʼ in Tuscarora) is a city in Ontario County, New York, United States. Its population was 10,545 at the 2010 census. It is the county seat of Ontario County; some administrative offices are at the county complex in the adjacent town of Hopewell.
The name Canandaigua is derived from the Seneca name of its historic village here, spelled variously Kanandarque, Ganandogan, Ga-nun-da-gwa, or Konondaigua, which was established long before any European Americans came to the area. In a modern transcription, the historic village is rendered as tganǫdæ:gwęh, which means "the chosen spot", or "at the chosen town".
The city is surrounded by the Town of Canandaigua. The City of Canandaigua is on the northern end of Canandaigua Lake, 24 miles (39 km) southeast of Rochester, 68 miles (109 km) west of Syracuse, and 93 miles (150 km) east of Buffalo. Parts of six neighboring towns also share the Canandaigua mailing address and 14424 ZIP code.
Developed near Canandaigua Lake at the site of the historic Seneca village Ganandogan, by the mid-19th century Canandaigua was an important railroad junction and home port for several steamboats that operated on the lake. After the Civil War, local industries included two brick works, the Lisk Manufacturing Company, several mills, and the regionally prominent McKechnie Brewery. The shire town of the original county of western New York, Canandaigua was the site of the trial of Susan B. Anthony in 1873 on charges of voting illegally because only men were allowed to vote.
In the 21st century, the town is a center for business, government, health care, and education.
