The "Dairy Belt" in the United States is primarily concentrated in the Midwest, where dairy farming is a key agricultural activity.

The Dairy Belt includes states like Wisconsin, Minnesota, and Michigan, which are known for their large-scale milk production and dairy industries. The region benefits from fertile soil, ample rainfall, and a climate conducive to growing the forage crops needed to feed dairy cattle. Wisconsin, often referred to as "America's Dairyland," is particularly famous for its cheese production. The Dairy Belt plays a crucial role in the U.S. dairy industry, contributing significantly to national milk, cheese, butter, and other dairy exports.
