Laramie County is a county located at the southeast corner of the U.S. state of Wyoming. As of the 2020 United States Census, the population was 100,512, making it the most populous county in Wyoming, but the least populous county in the United States to be the most populous in its state.

The county seat is Cheyenne, the state capital. The county lies west of the Nebraska state line and north of the Colorado state line.

Laramie County comprises the Cheyenne, WY Metropolitan Statistical Area.

The city of Laramie, Wyoming, is in neighboring Albany County.


Laramie County was originally created in 1867 as a county within the Dakota Territory. The county was named for Jacques La Ramee, a French-Canadian fur-trader. In late 1867, Laramie County lost territory when Sweetwater County was created.

In 1868, Laramie County also lost territory when Albany County and Carbon County were created. Laramie County became a county in the Wyoming Territory when the territorial government was formed in 1869. Crook County was created with land ceded by Laramie County in 1875. A few years later in 1888, Converse County was also formed from a portion of Laramie County. In 1911, Goshen and Platte Counties were formed from another part of Laramie County, and at that point the county achieved its current boundaries.

Many of the early occupations in the county were agriculturally based. The best known example would have to be Cattle farming; the Wyoming Stock Growers Association is one remaining example of this. However other animals were also raised.

Americans and foreigners were both attracted out over time, with places such as Burns being German immigrant filled early on.


According to the U.S. Census Bureau, the county has a total area of 2,688 square miles (6,960 km2), of which 2,686 square miles (6,960 km2) is land and 1.6 square miles (4.1 km2) (0.06%) is water.
