Davis County is a county located in the U.S. state of Utah. As of the 2010 census, the population was 306,479, making it the third-most populous county in Utah. Its county seat is Farmington, and its largest city is Layton. The county was created in 1850 and was named for Daniel C. Davis, captain in the Mormon Battalion.
Davis County was created on October 5, 1850, with Farmington designated as its county seat, because of its geographic location midway between boundaries at the Weber River on the north and the Jordan River on the south. During its first 50 years, Davis County grew slowly. With the advent of the Utah Central Rail Road in 1870, a transition to mechanized agriculture and a surge of commerce, banking, improved roads, new water systems, and electrification of homes began. However, by 1940, the population was barely 16,000.
With the establishment of Hill Air Force Base in northern Davis County, there was a surge of civilian employment after World War II. The county doubled in population between 1940 and 1950, and doubled again between 1950 and 1960 as part of the nationwide suburb boom that was occurring at the time. By 1990 there were 188,000 residents, and in 2000, there were 239,000. By 2030, the county is expected to have a population of about 360,000.
Today, most of the population resides in Layton, Bountiful, Kaysville, and Clearfield while most of the growth is concentrated in the northwest, northeast, and southwest portions of the county, and especially in such cities as Syracuse, Clinton, West Point, South Weber, and Woods Cross.
According to the U.S. Census Bureau, the county has a total area of 634 square miles (1,640 km2), of which 299 square miles (770 km2) is land and 335 square miles (870 km2) (53%) is water. It is the smallest county in Utah by land area and second smallest by total area.
The county lies generally between the Great Salt Lake on the west and the Wasatch Range on the east, which rises to a height of 9,707 feet (2,959 m) in the county at Thurston Peak. The Great Salt Lake in the west, which is surrounded by marshland and mudflats, lies at an average elevation of approximately 4,200 feet (1,300 m), varying depending on the water level, which can lead to drastic changes in the lake size due to its shallowness. Davis County includes Antelope Island, which is the largest island in the lake. The entire island is a state park, designated to protect natural scenery and especially wildlife on the island, which includes bighorn sheep, pronghorn, and a bison herd. The populated portion that lies between the Great Salt Lake and the Wasatch Range belongs to the Wasatch Front, a narrow stretch of land that restricts north-south transportation in the county.

Davis County lies in a semiarid climate zone. Snow is frequent during winter, with up to 90 in (230 cm) annually on high bench areas in the east and at least 60 inches (150 cm) on the valley floor. Annual precipitation averages between 18 and 25 inches (460 and 640 mm) in the county, with spring being the wettest season and summer the driest. Summers are hot, with several days each year averaging above 95 °F (35 °C). However, the humidity is low, making for comparatively comfortable temperatures. In winter, temperatures sometimes drop below 0 °F (−18 °C), but rarely for extended periods of time. Compared to Salt Lake County to the south, the weather in Davis County is extreme. Lake-effect snows hit the southern portion of the county harder, and even in non-lake-effect storms, the lack of a rain shadow in Davis County (much of Salt Lake County lies in the rain shadow of the Oquirrh Mountains) means that storms often hit Davis County harder. In addition, canyon winds from the east can sometimes cause devastating wind damage, and wind gusts above 100 mph (160 km/h) have been reported. This occurs when a powerful high pressure system situates itself over Wyoming, and is a common occurrence. Extreme wind events, however, have seemed to decline in frequency in recent years.

The most important road in the county is Interstate 15, which runs north-south through the center of the county. US-89 enters parallel to I-15 from Salt Lake County to the south and runs north through North Salt Lake and Bountiful as a city road before merging with I-15. It re-emerges again in Farmington near the Lagoon Amusement Park, heading along the eastern benches on the slopes of the Wasatch Range, entering Weber County near South Weber. US-89 is planned to eventually be upgraded to a freeway through eastern Layton north to its interchange with I-84 near the Weber County border. Congestion is a significant problem in the county, as east-west transportation is restricted by the narrow urban corridor and many of its citizens commute south to Salt Lake County.
To relieve congestion in the county, the Legacy Parkway began construction in 2006. Construction began near the US-89/I-15 interchange in Farmington in 2004, but was soon halted due to a lawsuit filed by environmentalists, who were concerned that the road would harm marshlands along the eastern edge of the Great Salt Lake and asked for a review of the completeness of the environmental impact statement. A settlement was reached in 2005 and the final injunction was lifted in 2006. The Legacy Parkway opened in 2008, running from the US-89/I-15 interchange in Farmington southward to connect with I-215 near the border with Salt Lake County. An extensive trail system, wetland protection measures, and landscaping were implemented along the highway in response to the environmentalist's concerns, in addition to a lower speed limit and a ban of semi-trailer trucks on the highway.
In 2008, the Utah Transit Authority opened the FrontRunner commuter rail line from Salt Lake City north to Ogden, serving the length of Davis County with stations in Woods Cross, Farmington, Layton, and Clearfield.
