Dell City is a city in Hudspeth County, Texas. The population was 365 at the time of the 2010 census, down from 413 at the time of the 2000 census. It is near the former location of Paulville, a failed Ron Paul-inspired Libertarian cooperative and planned community. It was incorporated in 1948, shortly after the discovery of an underground water supply by oil prospectors, which attracted farmers to the area. Its name is a reference to the nursery rhyme "The Farmer in the Dell."
