Main article: History of Cleveland County
Originally occupied by the Quapaw tribe, the Quapaw ceded the area to the U.S. Government soon after the Louisiana Purchase in 1818. During the late 1820s and 1830s, the area was given to the Creek and Seminole tribes after their forced removal from the southeastern United States. An agreement between the two tribes resulted in this area being part of the Seminole Nation, located west of the Creek Nation.
In 1866, these tribes were forced to cede the area to the Federal Government; the professed rationale was their siding with the Confederacy during the American Civil War. The area became part of the Unassigned Lands and was opened for white settlement on April 22, 1889.
After the passage of the Organic Act in 1890, Cleveland County was organized as County 3 (of 7) and Norman became the county seat. For a short time, Cleveland County was known as Little River County, until an election in 1890. The voters selected the name Cleveland in honor of President Grover Cleveland over the name Lincoln.
According to the U.S. Census Bureau, the county has a total area of 558 square miles (1,450 km2), of which 539 square miles (1,400 km2) is land and 19 square miles (49 km2) (3.5%) is water. It is the eighth smallest county in the state.
Cleveland County contains the reservoir Lake Thunderbird 5,349 acres (21.65 km2), constructed between 1962 and 1965. Its waters covered the previous settlement of Denver.
Cleveland County is the origin of the Little River, a tributary of the Canadian River, 90 miles (140 km) long. The Canadian River defines the southern border of Cleveland County.

Cleveland County is rather conservative for a county influenced by a college town. While most such counties swung heavily to the Democrats in the 1990s, Cleveland County has gone Republican in all but one presidential election since 1952, and last went Democratic for president in 1964. This closely mirrors the growing Republican trend in Oklahoma as a whole.

The US 77 James C. Nance Memorial Bridge linking Lexington and Purcell was originally built as a circa 1938 deck truss two-lane bridge and in 2019 rebuilt as a concrete pier four-lane bridge  crossing the Canadian River between Purcell and Lexington, Oklahoma. The bridge carries U.S. Route 77 (US-77) and Oklahoma State Highway 39 (SH-39) from McClain County to Cleveland County. The bridge is named for James C. Nance, longtime community newspaper chain publisher and Speaker of the Oklahoma House of Representatives, President Pro Tem of Oklahoma State Senate and Uniform Law Commissioner.
The Nance bridge allows travel time from Purcell (west side of the Canadian River) to Lexington (east side of the river) to be only three minutes by car, according to google maps. When the bridge was closed for emergency repairs, the same trip was 43 minutes when rerouted north to the nearest bridge, or one hour, four minutes when rerouted southeast to the nearest bridge.
The 1938 construction of this bridge enabled communities from West and Southwest (Byars, Cole, Dibble, Paoli, Pauls Valley, Purcell, Rosedale, and Wayne) side of the river to reach the communities on the East side of the river (Lexington, Slaughterville, and Wanette). Traffic using the bridge allows trade and commerce to freely flow in this retail trade area of southern McClain County, southern Cleveland County, Southern Pottawatomie County, and northern areas of Garvin County, and the eastern portion of Grady County. The bridge, rebuilt in 2019, features the same design elements with concrete post and wrought iron railings with protected turn lane and sidewalks.
According to the Oklahoma Department of Transportation, "History was made Friday July 26, 2019 in Purcell and Lexington, just as it was more than 80 years ago when the two cities celebrated the grand opening of a new bridge connecting their communities. The new US 77 Purcell/Lexington James C. Nance Bridge that links the twin cities, located less than one mile apart, fully opened to traffic with much fanfare on Friday, July 26, 2019, the culmination of a major two-year, expedited reconstruction project."
