Cisco, at the intersection of U.S. Highway 183 and Interstate Highway 20, in northwestern Eastland County, traces its history back to 1878 or 1879, when Rev. C. G. Stevens arrived in the area, established a post office and a church, and called the frontier settlement Red Gap. About six families were already living nearby, and W. T. Caldwell was running a store a half mile to the west. In 1881 the Houston and Texas Central Railway crossed the Texas and Pacific, which had come through the year before, at a point near Red Gap, and the settlement's inhabitants moved their town to the crossing. Three years later the town was officially recognized and a new post office granted; the town's name was changed to Cisco for John A. Cisco, a New York financier largely responsible for the building of the Houston and Texas Central. Railroads continued to influence the development of Cisco as the Texas and Pacific acquired lots in the town and sold them to immigrants attracted by brochures touting the town as the "Gate City of the West." Once settlers arrived, agricultural agents employed by the railroad advised them what and when to plant and on occasion provided the seed. During the 1880s a Mrs. Haws built and managed the first hotel, and Mrs. J. D. Alexander brought the first "millinery and fancy goods" to town. Following a practice common at the time, religious groups in Cisco met together for prayer meetings in the schoolhouse until they could build separate churches. By 1892 Cisco was a growing community with two newspapers, a bank, and an economy based on trade, ranching, fruit farming, and the limestone, coal, and iron ore available nearby. A broom factory and roller corn and flour mills were among the town's fifty-six businesses. In 1893 a tornado hit Cisco, killing twenty-eight people and destroying or damaging most of its homes and businesses.
Conrad Hilton started the Hilton Hotel chain with a single hotel bought in Cisco. Hilton came to Cisco to buy a bank, but the bank cost too much; so he purchased the Mobley Hotel in 1919. The hotel is now a local museum and community center.
During the 1920s, Cisco, like nearby Ranger, Eastland, and Desdemona, was a petroleum boomtown. Although Cisco played a relatively minor role in the Eastland County oil boom of 1919–21, its population grew rapidly at the time, with some estimates as high as 15,000; in the wake of the boom, Cisco adopted a city charter and built a new railroad station that cost $25,000, a value of $310,597.88 in 2015. 
In 1925, the first annual meeting of the West Texas Historical Association was held in Cisco. The association, formed in 1924, was then based at Hardin-Simmons University in Abilene but moved in 1998 to Texas Tech University in Lubbock.
The Santa Claus Bank Robbery occurred in Cisco on December 23, 1927, when Marshall Ratliff and his gang attempted to rob the First National Bank. As of August 2009, the bank site is occupied by an auto parts store, with a Texas Historical Commission sign commemorating the event.
Largest Concrete Swimming Pool in the World
Cisco in its early days was plagued with inadequate water supply. In the 1920s the Williamson Dam was built north of town, resulting in the formation of Lake Cisco. It was named after James Milton Williamson, long time mayor and survivor of the 1893 tornado. At its base was built what was billed as the largest concrete swimming pool in the world. The complex boasted a two story building with a skating rink upstairs, a zoo, an amusement park with rides, and a park. Bob Wills was only one of the celebrities to entertain there. For decades it was a major attraction for folks from miles around. The hollow dam was at one time open to the public but this is no longer the case. The pool closed in the 1970s and the vacant skating rink burned a few years later.
On May 9, 2015, an area just south of the city was hit by a large EF3 tornado, destroying several homes, killing 1, and critically injuring another.
