Boone County, Iowa is a county in the U.S. state of Iowa. It was established in 1846 and named after the American frontiersman Daniel Boone. The county seat and largest city is Boone, Iowa, and the county forms part of the Des Moines–West Des Moines metropolitan area. The county has an agricultural heritage and transportation links that connect it to regional markets such as Des Moines, Iowa and Ames, Iowa.
Territorial settlement of the area that became Boone County occurred during westward expansion after the Black Hawk Purchase and alongside broader migration trends driven by the Missouri Compromise era. The county was organized in 1846 during the same year Iowa achieved statehood. Early economic and infrastructural development was influenced by railroad construction by companies such as the Chicago and North Western Railway and the Chicago, Milwaukee, St. Paul and Pacific Railroad, which stimulated town founding including Boone, Iowa and Madrid, Iowa. Agricultural mechanization and the arrival of grain elevators linked local producers to commodity markets in Chicago and St. Louis, Missouri. The county experienced demographic shifts during the Dust Bowl and Great Depression, mirroring patterns seen in Midwestern United States counties, and later benefited from New Deal era programs associated with the Works Progress Administration and rural electrification initiatives promoted by the Rural Electrification Administration.
Boone County is located on the Des Moines River watershed and features glacially derived terrain common to central Iowa, including rolling prairies and river valleys shaped during the Wisconsin glaciation.

Major hydrological features include the Des Moines River and smaller tributaries that feed into the Mississippi River basin. The county's land use reflects intensive row-crop agriculture, interspersed with conservation areas and parks connected to statewide networks such as the Iowa Department of Natural Resources holdings and the Ledges State Park ecosystem corridor in the region. Transportation corridors such as Interstate 35 (nearby), U.S. Route 20, and U.S. Route 30 provide regional connectivity.

Ethnic and ancestral identities reflect immigrant waves associated with German American and Scandinavian Americans settlement patterns in the Upper Midwest, with more recent migration tied to domestic mobility within the United States.
Agriculture remains a primary economic driver, with production of corn, soybeans, and livestock connecting local farms to commodity exchanges such as the Chicago Board of Trade and input suppliers like John Deere. Agribusinesses, grain cooperatives, and ethanol production facilities link Boone County to the biofuel sector influenced by federal policies such as the Renewable Fuel Standard. Manufacturing and processing firms, small-scale food processors, and rural service providers complement the agricultural base, while retail and healthcare institutions in Boone, Iowa and Ogden, Iowa serve regional markets. Seasonal agricultural events and county fairs participate in networks exemplified by the Iowa State Fair and extension programming from Iowa State University.
Primary and secondary education is provided by several public school districts including Boone Community School District and Ogden Community School District, which follow statewide standards administered by the Iowa Department of Education.
