Nunda (pronounced "none-day") is a town in Livingston County, New York, United States.

The name is derived from Nunda-wa-ono, the name given to it by a group of the Seneca people who once lived in the hills and valleys along the Genesee River and Keshequa Creek within the present-day town.

In 1790, two small Seneca villages could be found opposite each other on the Chautauqua Hollow Trail which became State Street.

The population peaked at nearly 4,000 in the 1840s when the Genesee River Canal was built, which ran through the town until 1878.

New York State Route 70 crosses the south part of the town.

Interstate 390 passes 3 miles (5 km) northeast of the town and provides transportation north to the city of Rochester and southeast to the Finger Lakes Region.

20.5% of all households were made up of individuals, and 8.4% had someone living alone who was 65 years of age or older.

The word Keshequa is of Seneca origin and means "Spear in the Creek"[8]
