Collections of the Minnesota Historical Society for the Year 1867

The Minnesota Historical Society (MNHS) is a nonprofit educational and cultural institution dedicated to preserving the history of the U.S. state of Minnesota. It was founded by the territorial legislature in 1849, almost a decade before statehood. The Society is named in the Minnesota Constitution. It is headquartered in the Minnesota History Center in downtown St. Paul.

Although its focus is on Minnesota history it is not constrained by it. Its work on the North American fur trade has been recognized in Canada as well.

MNHS holds a collection of nearly 550,000 books, 37,000 maps, 250,000 photographs, 225,000 historical artifacts, 950,000 archaeological items, 38,000 cubic feet (1,100 m) of manuscripts, 45,000 cubic feet (1,300 m) of government records, 5,500 paintings, prints and drawings; and 1,300 moving image items.

MNopedia: The Minnesota Encyclopedia, is since 2011 an online "resource for reliable information about significant people, places, events, and things in Minnesota history", that is funded through a Legacy Amendment Arts and Cultural Heritage Fund grant and administered by the Minnesota Historical Society.
