Richford is a town in Tioga County, New York, United States. The population was 1,052 at the 2020 census. The town is named after Ezekial Rich, an early settler and benefactor of the town.
 The Town of Richford is the northernmost town in the county and is southeast of Ithaca.
 European-American settlement began around 1808 when Evan Harris brought his family here. Samuel Smith was the first to settle within the present village site in 1813. The first tavern was built in the village in 1817 at the site of the Richford Hotel (now the Richford Quickway) by Beriah Wells. Ezekial Rich moved to the town in 1821 when he purchased the tavern from Beriah Wells. He established a glove and mitten factory, and later opened a general store. The town was first formed from the Town of Berkshire as the "Town of Arlington" in 1831. In 1832 it changed its name to the Town of Richford.
 Local oral history links several properties in Richford with the Underground Railroad in the antebellum period, by which residents aided refugee slaves to reach freedom.
 In 1816, the Catskill Turnpike was brought through the village on its route to Ithaca and generated considerable traffic to the village.
This was the dominant route into or out of the village until 1869, when the Southern Central Railroad was completed between Auburn and Owego.

 Named in honor of the Clarks Seed Farm, this festival is held annually on the third Saturday of September to celebrate the significance of potato farming in Richford's history. Arts and crafts vendors are available as are games and races. The event is known for its potato-themed dishes, including potato ice-cream. This used to be made by Cornell University dairy and featured chocolate-covered potato sticks in vanilla ice cream.
