Sweetwater County's history began long before written records. In prehistoric times the landscape was swampy and inhabited by great dinosaurs. Thousands of years later Native Americans, mostly Shoshone and Ute, claimed the land. The first white men moving through the area with regularity were the mountain men. The first Rocky Mountain Rendezvous was held in 1825 in Sweetwater County, as was a later gathering in 1834 that is said to have been the largest rendezvous ever.

 Several major emigrant trails passed through the county including the Oregon, California, Mormon, Overland, and Cherokee Trails, as well as the Pony Express Trail, 1861 transcontinental telegraph line and Ben Holladay's Central Overland Express stage line. Vitally important to the history of the county was the coming of the transcontinental railroad in 1868. This was instrumental in the creation and development of Sweetwater County's two major population centers, Green River and Rock Springs.  Green River was the major railroad town due to the nearness of a water supply, while Rock Springs became the coal mining center of the county.
