There are 29 [[County (United States)|counties]] in the U.S. state of [[Utah]].

In 1849, the provisional [[State of Deseret]] established seven counties: [[Davis County, Utah|Davis]], [[Iron County, Utah|Iron]], [[Sanpete County, Utah|Sanpete]], [[Salt Lake County, Utah|Salt Lake]], [[Tooele County, Utah|Tooele]], [[Utah County, Utah|Utah]], and [[Weber County, Utah|Weber]].<ref>{{Cite book |last=Fisher |first=Richard Swainson |url=https://archive.org/details/newcompletestati01fish |title=A new and complete statistical gazetteer of the United States of America |publisher=J.H.

Over a 40-year period (1854–1894), the Utah Territorial Legislature established most of the counties that exist today. In the early 20th century, after Utah had become a state, the final two counties were created: [[Duchesne County, Utah|Duchesne]] by [[Governor of Utah|gubernatorial]] proclamation (1913) and [[Daggett County, Utah|Daggett]] by popular vote (1917).<ref name="CountyFormation" /> Present-day Duchesne County encompassed an [[Indian reservation]] that was created in 1861. The reservation was opened to [[Homestead Act|homesteaders]] in 1905 and the county was created in 1913.<ref>{{Cite web |title=Duchesne County, Utah |url=http://pioneer.utah.gov/research/utah_counties/duchesne.html |access-date=May 1, 2010 |website=Pioneer, Utah's Online Library |publisher=State of Utah}}</ref> Due to dangerous roads, mountainous terrain, and bad weather preventing travel via a direct route, 19th-century residents in present-day Daggett County had to travel {{convert|400|to|800|mi|km}} on both stage and rail to conduct business in [[Vernal, Utah|Vernal]], the county seat for [[Uintah County, Utah|Uintah County]] a mere {{convert|50|mi}} away. In 1917, all Uintah County residents voted to create Daggett County.<ref>{{Cite book |last=Industrial Commission of Utah |url=https://archive.org/details/bub_gb_3xooAAAAYAAJ |title=Report of the Industrial Commission of Utah |publisher=Inland Publishing Company |year=1920 |location=Kaysville, Utah |page=[https://archive.org/details/bub_gb_3xooAAAAYAAJ/page/n344 346] |access-date=May 1, 2010}}</ref>

Based on 2024 United States Census data, the population of Utah was 3,503,613.  Just under 75% of Utah's population is concentrated along four [[Wasatch Front]] counties: Salt Lake, Utah, Davis, and Weber.  Salt Lake County was the largest county in the state with a population of 1,216,274, followed by Utah County with 747,234, Davis County with 378,470 and Weber County with 276,118.  Daggett County was the least populated with 956 people.  The largest county in land area is [[San Juan County, Utah|San Juan County]] with {{convert|7821|mi2|km2}} and Davis County is the smallest with {{convert|304|mi2|km2}}.<ref name="2020census">{{Cite web |title=U.S. Census Bureau QuickFacts: Utah |url=https://www.census.gov/quickfacts/fact/table/UT/PST045219 |access-date=March 14, 2025 |publisher=U.S. Census Bureau}}</ref>

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 county.<ref>{{Cite web |title=FIPS Publish 6-4 |url=http://www.itl.nist.gov/fipspubs/fip6-4.htm |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 |access-date=July 20, 2007 |publisher=National Institute of Standards and Technology}}</ref>  Utah's FIPS code is 49, which when combined with any county code would be written as 49XXX.  In the FIPS code column in the table below, each FIPS code links to the most current census data for that county.<ref name="FIPS" />

The Utah Code (Title 17, Chapter 50, Part 5) divides the counties into six classes by population:<ref>[https://www.lawserver.com/law/state/utah/ut-code/utah_code_17-50-501 Utah Code 17-50-501. Classification of counties]</ref>
* First class: Population of 1,000,000 or more. Only one county - Salt Lake - is first class.
* Second class: Population between 175,000 and 1,000,000. Four counties.
* Third class: Population between 40,000 and 175,000. Five counties.
* Fourth class: Population between 11,000 and 40,000. Ten counties.
* Fifth class: Population between 4,000 and 11,000. Five counties.
* Sixth class: Population below 4,000. Four counties.

The county classes, for example, are used in the Utah legislature in crafting of legislation to distinguish between more urban and rural areas, such as important yet subtle distinctions in how revenue can be distributed. Usually, a bill intended to benefit rural counties would target the counties of the fourth, fifth and sixth class.<ref>[https://www.hjnews.com/allaccess/one-of-the-big-boys-cache-county-expected-to-move/article_d1b0c2ac-7f55-5283-954a-c5c2cc5ed911.html 'One of the big boys': Cache County expected to move up in class in 2019, based on population growth]</ref>

Under Utah Code (Title 17, Chapter 52a, Part 2), Utah counties are permitted to choose one of four forms of county government:<ref>[https://www.lawserver.com/law/state/utah/ut-code/utah_code_title_17_chapter_52a_part_2 Utah Code > Title 17 > Chapter 52a > Part 2 – Forms of County Government]</ref> a three-member full-time commission; a five or seven member expanded commission; a three to nine member (odd-numbered) part-time council with a full-time elected county mayor or a three to nine member (odd-numbered) part-time council with a full-time manager appointed by the council. 23 out of 29 counties are ruled by the standard three-member commission. Of the other six, Cache County was the first change in 1988 to a seven-member council with an elected mayor. Grand County adopted a seven-member council with appointed manager in 1992, followed by Morgan County in 1999 and Wasatch County in 2003. In 1998, Salt Lake County residents approved adopting a nine-member council with elected mayor that began work in 2001.<ref>[https://www.deseret.com/2003/8/25/19743959/changes-in-state-s-county-governments Changes in state's county governments]</ref> Summit County adopted a five-member council with an appointed manager in 2006.<ref>[https://www.parkrecord.com/news/guest-editorial-111/ Guest Editorial]</ref>
