Oakfield is a town in Genesee County, New York, United States.

The name of the town is derived from a number of trees, including the oak.

The manner in which they cut down the trees on their land gave rise to the phrase "Oak Orchard," which has current usage in the area.

In 1858, the community of Caryville set itself off from the town by incorporating as the village of Oakfield.

Oak Orchard Creek flows across the north part of the town.
