Fort Davis is a census-designated place (CDP) in Jeff Davis County, Texas, United States. The population was 1,050 at the 2000 census and 1,041 according to a 2007 estimate. It is the county seat of Jeff Davis County. It was the site of Fort Davis established in 1854 on the San Antonio-El Paso Road through west Texas and named after Jefferson Davis, who was then the Secretary of War under President Franklin Pierce.

Fort Davis National Historic Site was established in 1961 in order to protect one of the best remaining examples of a United States Army fort in the southwestern United States. From 1854 to 1891, Fort Davis was strategically located to protect emigrants, mail coaches, and freight wagons on the Trans-Pecos portion of the San Antonio-El Paso Road and the Chihuahua Trail, and to control activities on the southern stem of the Great Comanche War Trail and Mescalero Apache war trails. During the American Civil War, Confederate States Army troops manned the fort which was attacked on August 9, 1861 by Mescalero Apaches. The native warriors attacked the garrison's livestock herd, killed two guards and made off with about 100 horses and or cattle. Fort Davis is important in understanding the presence of African Americans in the West and in the frontier military because the 24th and 25th U.S. Infantry and the 9th and 10th U.S. Cavalry, all-black regiments (known as the Buffalo Soldiers), which were established after the American Civil War, were stationed at the post.
