Fort Croghan was the third of the first four forts established by the United States government to protect settlers from hostile Indians along the Texas frontier. From its establishment on March 18, 1849, by Lt. C.H. Taylor (Company A, Second Dragoons) until it was abandoned in 1855, Fort Croghan was home to Company C, 8th Infantry, U.S.A. (mounted), and eventually became the headquarters of the Second Dragoon Regiment. Part of a chain of forts extending from Fort Worth to Fort Inge near present-day Uvalde, the fort was named for Colonel George Croghan. The fort originally covered some 50 acres (20 ha) near the present-day city of Burnet, Texas, extending from Hamilton Creek up and over Post Mountain. Today, a small section exists due to the efforts of the Burnet County Historical Society, which raised money in the 1960s to purchase this portion of the old fort.

Fort Croghan is located in Burnet County, United States. Its specific geographic coordinates are latitude 30.7569 and longitude -98.2375.
