The Mesabi Iron Range is a mining district and mountain range in northeastern Minnesota following an elongate trend containing large deposits of iron ore. It is the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota. First described in 1866, it is the chief iron ore mining district in the United States. The district is located largely in Itasca and Saint Louis counties. It has been extensively worked since 1892, and has seen a transition from high-grade direct shipping ores through gravity concentrates to the current industry exclusively producing iron ore (taconite) pellets. Production has been dominantly controlled by vertically integrated steelmakers since 1901, and therefore is dictated largely by US ironmaking capacity and demand.

Minnesota is a state in the Upper Midwestern region of the United States. It is the 12th largest U.S. state in area and the 22nd most populous, with over 5.75 million residents. Minnesota is known as the "Land of 10,000 Lakes" but actually has 14,380 bodies of fresh water covering at least ten acres each; roughly a third of the state is forested; much of the remainder is prairie and farmland. More than 60% of Minnesotans live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", the state's main political, economic, and cultural hub and the 16th-largest metropolitan area in the U.S. Other minor metropolitan and micropolitan statistical areas include Duluth, Mankato, Moorhead, Rochester, and St. Cloud.
