There are 23 counties in the U.S. state of Wyoming. There were originally five counties in the Wyoming Territory: Laramie and Carter, established in 1867; Carbon and Albany established in 1868; and Uinta, and annexed portion of Utah and Idaho, extending from Montana (including Yellowstone Park) to the Wyoming–Utah boundary.[1] On July 10, 1890, Wyoming was admitted to the Union with thirteen counties in it. Ten more counties were created after statehood.[1]

Two counties were renamed after their creation. Carter County was renamed Sweetwater County on December 1, 1869.[2] Pease County, formed in 1875, was renamed Johnson County in 1879.[3]
The Federal Information Processing Standard (FIPS) code, which is used by the United States government to uniquely identify states and counties, is provided with each entry.[4] Wyoming's code is 56, which when combined with any county code would be written as 56XXX. The FIPS code for each county links to census data for that county.[5]
