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.{{cite web |url=http://wyoming.gov/general/history.asp |title=General Facts About Wyoming |access-date=July 20, 2007 |work=State of Wyoming |archive-url = https://web.archive.org/web/20070512143401/http://wyoming.gov/general/history.asp |archive-date = May 12, 2007}} On July 10, 1890, Wyoming was admitted to the Union with thirteen counties in it. Ten more counties were created after statehood.
Two counties were renamed after their creation. Carter County was renamed Sweetwater County on December 1, 1869.{{cite web| url=http://wyoarchives.state.wy.us/databases/county/carter/carter.htm |title=Carter County Records |access-date=July 20, 2007 |work=Wyoming State Archives |archive-url = https://web.archive.org/web/20080503190151/http://wyoarchives.state.wy.us/databases/county/carter/carter.htm |archive-date = May 3, 2008}} Pease County, formed in 1875, was renamed Johnson County in 1879.{{cite web |url=http://www.rootsweb.com/~wyoming/mn-counties.htm |title=Wyoming Counties |access-date=July 20, 2007 |work=American Local History Network |publisher=RootsWeb.com}}
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.{{cite web|url= http://www.itl.nist.gov/fipspubs/fip6-4.htm|title= FIPS Publish 6-4|publisher= National Institute of Standards and Technology|access-date= July 20, 2007|url-status= dead|archive-url= https://web.archive.org/web/20130929074056/http://www.itl.nist.gov/fipspubs/fip6-4.htm|archive-date= September 29, 2013}} 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.{{cite web |url=http://www.epa.gov/enviro/html/codes/wy.html |title=EPA County FIPS Code Listing |access-date=July 20, 2007 |work=US Environmental Protection Agency |url-status=dead |archive-url=https://web.archive.org/web/20130730055653/http://www.epa.gov/enviro/html/codes/wy.html |archive-date=July 30, 2013 }}
