Great Northern 2584 is a 4-8-4 "Northern" type steam locomotive built by the Baldwin Locomotive Works in Philadelphia, Pennsylvania in March 1930 for the Great Northern Railway (GN) as a member of the S-2 class.

The locomotive was built for fast passenger service and was assigned to pull the Great Northern's mainline passenger trains such as the Empire Builder and Oriental Limited. It was then retired in December 1957 and put on display at the Havre station in Havre, Montana for display in May 1964. It is the sole surviving Great Northern S-2 Class "Northern", the sole surviving Great Northern "Northern" type and the largest surviving Great Northern steam locomotive.
