Weber County ( // WEE-bər) is a county in the U.S. state of Utah. As of the 2010 census, the population was 231,236,  making it Utah's fourth-most populous county. Its county seat and largest city is Ogden,  the home of Weber State University. The county was formed in 1850  and named after the Weber River, which in turn was named for John Henry Weber (1779–1859), a fur trapper and trader in the area in the mid-1820s.
Historically Weber County stretched from the California, Oregon, Utah Territory border in the north west, to the current boundary in the south east.  As Nevada and the State of Utah evolved, Weber County shrunk to its current size. It occupies a stretch of the Wasatch Front, part of the eastern shores of Great Salt Lake, and much of the rugged Wasatch Mountains.
According to the U.S. Census Bureau, the county has an area of 659 square miles (1,710 km2), of which 576 square miles (1,490 km2) is land and 83 square miles (210 km2) (13%) is water.  It is the second-smallest county in Utah by land area and third-smallest by total area.
The county extends from high in the Wasatch Range in the east into a portion of the Great Salt Lake to the west. The Weber and Ogden rivers and their tributaries run through its valleys. The Weber County Surveyor's office divides the county into two regions, the "Lower Valley" and the "Upper Valley", divided by the ridge of the Wasatch front range south through the county. The "Lower Valley" is the more county's populous part and is next to the Great Salt Lake. The "Upper Valley" is the eastern part of the county and consists mostly of the Ogden Valley, the watershed of the Ogden River.
