Morgan County is a county in the U.S. state of Utah. As of the 2010 census, the population was 9,469. Its county seat and largest city is Morgan. The county was named for Jedediah Morgan Grant, father of Heber J. Grant, who served as president of The Church of Jesus Christ of Latter-day Saints.

Morgan County is part of the Ogden-Clearfield, UT Metropolitan Statistical Area as well as the Salt Lake City-Provo-Orem, UT Combined Statistical Area.


An early route of the Hastings Cutoff ran through the Morgan Valley and down through a narrow gorge in Weber Canyon. The Donner Party avoided going through the Morgan Valley in order to speed up their journey. However, their alternate route proved more time-consuming.

In 1855, Charles Sreeve Peterson and his family became the first white settlers to take up permanent residence in the Morgan Valley after cutting a road through Weber Canyon.


According to the U.S. Census Bureau, the county has an area of 611 square miles (1,580 km2), of which 609 square miles (1,580 km2) is land and 1.7 square miles (4.4 km2) (0.3%) is water. It is Utah's third-smallest county by land area and smallest by total area.
