Carbon County was organized in 1868.
Originally about 3,400 square miles (8,800 km2) in the center of Carbon County were once part of the Spanish Empire, then part of the Republic of Texas (1835-1845) and part of the State of Texas until 1852 when the northernmost part of that state was ceded to the U.S. government. This area is defined by the 42nd parallel on the north, and straight lines south from there to the headwaters of the Arkansas river on the east and the headwaters of the Rio Grande on the west. The documents defining that area include the Adams-Onís Treaty of 1819, the 1824 Constitution of Mexico, and the 1845 "Joint Resolution for the Admission of the State of Texas into the Union".
Carbon County was organized December 16, 1868, from Laramie County in Dakota Territory, which at the time had jurisdiction over part of modern-day Wyoming.  It became a county in Wyoming Territory when that territory's government was formally organized on May 19, 1869.  
In 1868, the Union Pacific Railroad opened the first coal mine in Carbon County, and the county was named for its extensive coal deposits.  In 1875, Carbon County lost territory when Johnson County was created by the legislature of the Wyoming Territory. Natrona County was created with land ceded by Carbon County in 1888. The boundaries of the county were final at that time except for minor adjustments in 1911.
From 1978-1982, Carbon County was represented in the Wyoming House of Representatives by Democrat Thomas E. Trowbridge (1930-2009) of Saratoga, a Nebraska native. From 1982-1986, Trowbridge was a member of the Wyoming State Senate. He was later appointed by Governor Mike Sullivan to the Wyoming State Board of Equalization. Trowbridge's father, Elton Trowbridge, held the state House seat from Carbon County from 1961 until his death in office in 1974.
George R. Salisbury, Jr., a rancher from Savery, represented Carbon County in the Wyoming House from 1975-1986. He was succeeded in office by his son-in-law and fellow Democrat, Patrick F. O'Toole, also a Savery rancher.
According to the U.S. Census Bureau, the county has a total area of 7,964 square miles (20,630 km2), of which 7,898 square miles (20,460 km2) is land and 66 square miles (170 km2) (2.0%) is water.  It is the third-largest county in Wyoming by area.

During the twentieth century, owing to its considerable unionized mining population, Carbon County tended to be much more Democratic than the rest of powerfully Republican Wyoming. It was one of three Wyoming counties to vote for John F. Kennedy in 1960 and one of two to vote for Hubert Humphrey in 1968, whilst Dwight D. Eisenhower only won the county narrowly in his two landslide Presidential wins. The Democratic Party’s hostility towards the coal industry, however, has made the county nearly as Republican as the rest of Wyoming in the twenty-first century.
The Wyoming State Penitentiary, operated by the Wyoming Department of Corrections, is located in Rawlins.  The facility was operated by the Wyoming Board of Charities and Reform until that agency was dissolved as a result of a state constitutional amendment passed in November 1990.
