Cisco is a city in Eastland County, Texas, United States. The population was 3,851 at the 2000 census.
Conrad Hilton started the Hilton Hotel chain with a single hotel bought in Cisco. Hilton came to Cisco to buy a bank, but the bank cost too much; so he purchased the Mobley Hotel in 1919. The hotel is now a local museum and community center.
During the 1920s, Cisco, like nearby Ranger, Eastland, and Desdemona, was a petroleum boomtown.
