The Great Northern Railway was an American Class I railroad. Running from Saint Paul, Minnesota, to Seattle, Washington, it was the creation of 19th century railroad entrepreneur James J. Hill and was developed from the Saint Paul & Pacific Railroad. The Great Northern's route was the northernmost transcontinental railroad route in the U.S. The Great Northern was built in stages, slowly to create profitable lines, before extending the road further into the undeveloped Western territories. In a series of the earliest public relations campaigns, contests were held to promote interest in the railroad and the ranchlands along its route. Fred J. Adams used promotional incentives such as feed and seed donations to farmers getting started along the line. Contests were all-inclusive, from largest farm animals to largest freight carload capacity and were promoted heavily to immigrants & newcomers from the East.

The earliest predecessor railroad to the GN was the St. Paul & Pacific Railroad, a bankrupt railroad with a small amount of track in the state of Minnesota. James Jerome Hill convinced John S. Kennedy (a New York banker), Norman Kittson (Hill's friend and a wealthy fur trader), Donald Smith (an executive with Canada's Hudson's Bay Company), George Stephen (Smith's cousin and president of the Bank of Montreal), and others to invest $5.5 million in purchasing the railroad. On March 13, 1878, the road's creditors formally signed an agreement transferring their bonds and control of the railroad to Hill's investment group. On September 18, 1889, Hill changed the name of the Minneapolis and St. Cloud Railway (a railroad which existed primarily on paper, but which held very extensive land grants throughout the Midwest and Pacific Northwest) to the Great Northern Railway. On February 1, 1890, he transferred ownership of the StPM&M, Montana Central Railway, and other rail systems he owned to the Great Northern.

The Great Northern had branches that ran north to the Canada–US border in Minnesota, North Dakota, and Montana. It also had branches that ran to Superior, Wisconsin, and Butte, Montana, connecting with the iron mining fields of Minnesota and copper mines of Montana. In 1898 Hill purchased control of large parts of the Messabe Range iron mining district in Minnesota, along with its rail lines. The Great Northern began large-scale shipment of ore to the steel mills of the Midwest. At its height, Great Northern operated over 8,000 miles.
