Archeologic evidence suggests that portions of the Uinta Basin have been inhabited by Archaic peoples and Fremont peoples. By the time of recorded history its inhabitants were the Ute people. The first known traverse by non-Indians was made by Fathers Dominguez and Escalante (1776), as they sought to establish a land route between California and Spanish America. 
By the early nineteenth century, occasional fur trappers entered the Basin. In 1831-32 Antoine Robidoux, a French trapper licensed by the Mexican government, established a trading post near present-day Whiterocks. He abandoned the effort in 1844.
In 1847 the Great Salt Lake Valley, still a property of Mexico, was first colonized by Brigham Young and his followers. In 1861 Young dispatched an exploring party to the Uinta Basin; they reported that "that section of country lying between the Wasatch Mountains and the eastern boundary of the territory, and south of Green River country, was one vast contiguity of waste and measurably valueless." Young made no further effort to colonize the area.
In 1861 US President Abraham Lincoln created the Uintah and Ouray Indian Reservation, reserved for the use and habitation of Utah and Colorado Indians. In the 1880s the Uncompahgre Reservation was created in the southern portion of present-day Uintah County. Ashley Valley was not part of either Reservation, and by 1880 enough ranchers and farmers had settled there that the Territorial Legislature created Uintah County (most of which had previously been part of Wasatch County, with the county seat at Ashley (now an abandoned area some three miles (5 km) from present-day Vernal).
Gilsonite was discovered in 1888 at Bonanza, in central Uintah County. This was on Reservation land, but miners pressured the US government to remove some 7000 acres (11 square miles; 28 km²) for mining use. Mining and its associated activities (including relative lawlessness) rapidly boomed in that area. 
The northern boundary of Uintah County originally extended to the north border of Utah. In 1918 the extreme northern portion (lying north of the Uinta Mountain watershed divide) was split off to form Daggett County, Utah.
Uintah County is centered in the Uintah Basin, which runs from western Colorado on the east to the Wasatch Mountains on the west, and from the Uinta Mountains on the north to the Roan Plateau on the south. This basin was formed by a prehistoric lake ("Uinta Lake") during the late Tertiary period.
The county's geography ranges from high mountain terrain (Uinta Mountains) to the fertile Ashley Valley (site of the county seat), to a rugged and desolate canyonland which includes the Dinosaur National Monument, to desolate and largely uninhabited hills in the south ("The Bookcliffs" to locals; officially Roan Plateau).

A significant portion of west Uintah County is taken up by the Uintah and Ouray Indian Reservation.  The Ute Tribe's headquarters is in Fort Duchesne. Much of the rest of the county is land owned by the Ashley National Forest and the Bureau of Land Management. There is relatively little private land in the county.
Discovery of significant dinosaur and other pre-historic remains on the eastern edge of the county caused nationwide interest, which culminated in establishment of Dinosaur National Monument. In addition to the large Visitor Center at the Monument's Jensen site, a natural history museum, the Utah Field House of Natural History State Park Museum, showcasing some of the area's finds, was established in Vernal by the State of Utah. 
Located just outside Vernal, the Vernal-Regional Airport provides daily scheduled air service to Denver, Colorado via Denver International Airport. Service is provided through United Express, operated by Skywest airlines. Fixed-Base Operator (FBO) service is also available.
