The community was founded in 1876 after the organization of Kimble County earlier that year. The original town site was named "Denman" after Marcellus Denman, who had surveyed and platted the new community. The name was quickly changed to "Junction City". In late 1876, Junction City won the designation of county seat from the unsuccessful and flood-prone settlement of Kimbleville. By 1879, a drugstore, livery stable, sawmill, and a few general stores were active in the community. Around 300 people were living in Junction City in 1882. The West Texas, Kimble County's first newspaper, began publishing in 1882. The county courthouse and its records were lost to a fire in 1884. A second, two-story brick and stone courthouse was partially destroyed in an 1888 fire, but was repaired and remained in use until 1929, when the present courthouse was constructed. In 1894, Junction City became known simply as "Junction". Infrastructure improvements marked the decade of the 1890s. Businessman Ernest Holekamp provided the city's first waterworks with a canal dug from the South Llano to Junction in 1895. A dam was built in 1896 on the South Llano River to provide power and water to the city and irrigation to surrounding lands.

The population stood at 536 in 1900. Four Mile Dam, a more permanent and extensive dam, was completed in 1904. Junction continued to grow rapidly, with around 800 residents living in the community in 1910. That figure had grown to 1,250 by 1920. By the late 1920s, citizens felt the need for the benefits of a municipal government. On August 27, 1927, H.O. Denman and 152 others presented an incorporation petition to Kimble County Judge J.B. Randolph. In the election, 390 votes were cast: 274 (70%) "For Incorporation" and 116 (30%) "Against Incorporation". A city officers' election took place on October 13, 1927, with Ernest Holekamp elected as Junction's first mayor.

During the mid-1920s, highway connections from Junction to Menard and San Angelo were made available. A sewer system was built in 1929. In the 1930 census, the city recorded 1,415 residents. Junction was the chief shipping and commercial center of Kimble County, as well as a tourist resort and hunting center. A new municipal building and fire station were opened in 1939 and 1940, respectively. In the mid-1940s, the cedar-oil business enhanced the economy, but the city's growth slowed. Throughout the latter half of the 20th century and into the 21st, Junction's population continued to hover around 2,600.
