Morgan County, Utah was formed on January 17, 1862, by the Utah Territorial Legislature. It was named after Jedediah Morgan Grant, a pioneer and father of Heber J. Grant.
The first pioneer settlers in Morgan County were Charles Sreeve Peterson and his family, who arrived in 1855. They built a cabin near the confluence of the Weber River and Peterson Creek. Other settlers soon followed, and by 1862, there were fifteen settlements in what is now Morgan County.
Morgan County is located in the Wasatch Mountains, and its economy is based on agriculture, manufacturing, and tourism. The county is home to several state parks, including Lost Creek State Park and East Canyon State Park.
Morgan county has an estimated population of 12,295 per the 2020 U.S. Census.
