Jacksboro was first settled in the 1850s, with newcomers attracted by land offers from the Texas Emigration and Land Office. Originally called "Mesquiteville", the community grew up along the banks of Lost Creek and spread out over the pastureland between Lost Creek and the waters of the West Fork of Keechi Creek. It was renamed "Jacksboro" in 1858, when it became the county seat, in honor of brothers William and Patrick Jack, veterans of the Texas Revolution. Regular postal service began in 1859. Jacksboro was located on one route of the Butterfield Overland Mail.

The county was one of the few in Texas to vote against secession before the Civil War. It continued to suffer from Native American raids until Fort Richardson was built and garrisoned in 1870 south of Jacksboro. The town gained national attention in 1871 when two Kiowa chiefs, Satanta and Big Tree, were tried for murder there.

The arrival of the Chicago, Rock Island & Texas Railroad in 1898 increased the town's commercial importance to the surrounding region, enhancing it as a center of trade. The completion of highways and other roads later on also connected the town to other markets.

Fort Richardson State Historical Park is in the southern part of the city. Jacksboro claims to have the first state 4-H club, formed in the 1910s.

On March 21, 2022, an EF3 tornado struck the town causing damage to around 80 homes and heavily damaging the high school. Nine people were injured.
