Cundiff is an unincorporated community in Jack County, Texas, United States.

After the Indians were driven out of Jack County in the middle of the 1870s, people started moving back to the Cundiff region.

Walker Moore established a townsite in 1891 and christened it Cundiff after dividing a large area of land into several farms.
