Blue Hill Township is located in north central Sherburne County, Minnesota, United States. Blue Hill Township was presumably settled in 1856. It was organized in 1877, having previously been a part of Baldwin Township. Blue Hill Township is named after a lone hill in the Sherburne National Wildlife Refuge, called Blue Mound, which rises about 75 feet above the surrounding county and can be seen from a great distance. In recent years the population has increased from 762 (2000 census) to 2507 (2020 census).
