Walker County is a county located in the east central section of the U.S. state of Texas. As of the 2020 census, its population was 76,400. Its county seat is Huntsville. Initially, Walker County was named for Robert J. Walker, a legislator from Mississippi who introduced into the United States Congress the resolution to annex Texas. Walker later supported the U.S. during its Civil War and earned some enmity for it. In order to keep the county's name, the state renamed it for Samuel H. Walker, a Texas Ranger and soldier in the United States Army.
