Counties of Minnesota: overview and key facts

Structure and functions

Each county typically has an elected board or commission and officials such as a sheriff, auditor, treasurer and county attorney. County seats—often a town or city centrally located within the county—house courthouses and administrative offices. County size and responsibilities vary: some are dominated by a single large city and metropolitan services, while others cover extensive rural territory with agricultural, forestry or resource-management duties.

Notable counties

Within the state, the Twin Cities area is centered in counties like Hennepin (Minneapolis) and Ramsey (St. Paul), which are among the most populous and urbanized. In contrast, St. Louis County in northeastern Minnesota is notable for its large land area and for including parts of the Iron Range and the Boundary Waters region. Smaller or more remote counties have very different economic and service needs.

History and names

The pattern of counties evolved during and after territorial times, with many counties established in the mid-19th century as settlement expanded; Minnesota became a state in 1858. County names reflect a mix of influences, including Indigenous place names, U.S. presidents and politicians, early explorers and geographic features.

Regions, economy and uses

Counties are commonly grouped by region—Twin Cities metropolitan, northern Arrowhead and Iron Range, central agricultural belts, and the southeastern river valleys. Their economies range from metropolitan commerce and industry to farming, mining, tourism and forestry. Counties are essential for planning, emergency management, social services and local infrastructure.
