Fort Cobb is a town in Caddo County, Oklahoma, United States.

[4] Fort Cobb was established as a U.S. Army frontier post in Indian Territory on October 1, 1859, 1 mile (1.6 km) east of the present location of the town.

The fort was named after Secretary of the Treasury Howell Cobb, a friend of the founding officer, Major William Emory.

The post was later occupied by both Southern and Northern forces during the Civil War, the Union taking control of the fort as part of the 1862 Tonkawa massacre.

Later, Lieutenant Colonel George Armstrong Custer's command was encamped at Fort Cobb from December 18, 1868, to January 6, 1869.

The largest number of residents was 827 in 1930, but soon began a steep decline because of the Great Depression and World War II.

[7] Fort Cobb is located west of the center of Caddo County in the valley of the Washita River.

Construction of Fort Cobb Dam and the adjacent park opened the town to tourism as a major economic force in the second half of the century.
