MDU Resources Group, Inc. (: MDU) is a U.S. diversified energy company, with electric and natural gas utility distribution operations in Idaho, Minnesota, Montana, North Dakota, Oregon, South Dakota, Washington, and Wyoming.

MDU Resources got its start in 1924 as the Minnesota Northern Power Company. Its founder, Rolland Heskett, had previously been involved with utilities in Wisconsin and northeast Minnesota (the forerunners of Wisconsin Public Service Corporation and Minnesota Power, respectively). The Minnesota Northern Power holdings initially consisted of the electric utility at Cushing, Oklahoma (quickly sold off to Oklahoma Gas & Electric), Minnesota Electric Light & Power Company, which served the Bemidji, Minnesota area (sold in 1925 to the W. B. Foshay interests—this property today comprises Otter Tail Power's Bemidji division), the Eastern Montana Light & Power Company, which was centered around Sidney and Glendive, Montana, and the Eastern Montana Utilities Co. which was based in Fairview, Montana. The two 'Eastern Montana' utilities became the nucleus of MDU's operations.

Initially, Minnesota Northern was only in the business of selling electric power, but entered the gas business following discovery of deposits in Eastern Montana. As Minnesota Northern expanded across Eastern Montana and western North Dakota, it acquired the electric franchise for Miles City, Montana after an acquisition struggle with the Montana Power Company.
