List of counties in Wyoming
This is a list of counties in Wyoming. 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, an 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.[1]
Three counties were renamed after their creation. Carter County was renamed Sweetwater County on December 1, 1869.[2] Hanover County existed for seven days in 1911 before it was renamed Washakie County.[3] 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]
