Jacksboro is a city in north-central Texas and the county seat of Jack County. Its population was 4,184 at the 2020 census, and it sits at a notable crossroads where U.S. Highways 281 and 380 and Texas State Highways 114 and 199 intersect. The city anchors a county long shaped by ranching and the frontier. The community's signature landmark is Fort Richardson, a United States Army post established in 1868 as the northernmost fort in Texas to protect settlers from Comanche and Kiowa raids. The fort was active until 1878, and its surviving buildings are now preserved within Fort Richardson State Park and Historic Site, along with the Lost Creek Reservoir State Trailway. The park's reenactments and historic buildings give Jacksboro a distinctive connection to Texas frontier history. Outdoor recreation is central to life in the area. The state park offers hiking, camping, and historic tours, while Quarry Lake and Lake Jacksboro provide fishing within the park's north unit. Hunting, ranching, and country living shape the surrounding county's economy and character, and the town's historic courthouse square keeps its county-seat role at the center of community life. Public schools are operated by the Jacksboro Independent School District, which serves the city and much of Jack County. Housing in Jacksboro mixes older homes near the square with ranch-style houses and rural acreage beyond the town limits, reflecting its small-town, agricultural setting. The city sits along the Jacksboro Highway between Fort Worth and Wichita Falls, and its position at a four-highway junction makes it a natural crossroads for the region. The result is a quiet, historically rooted county-seat community offering open space, frontier heritage, and a strong sense of small-town identity in North Texas.
