The Great Northern Tunnel is a 1-mile (1.6 km) double-tracked railway tunnel under downtown Seattle, Washington, completed by the Great Northern Railway in 1905, and now owned by the BNSF Railway, on its Scenic Subdivision. At the time it was built, it was the tallest and widest tunnel in the United States, at 28 feet (8.5 m) high and 30 feet (9.1 m) wide.[2]

The southern portal is just north of King Street Station, and the northern in Victor Steinbrueck Park, between Virginia and Pine Streets. The Downtown Seattle Transit Tunnel passes four feet below the Great Northern Tunnel.[3]

A plaque that reads, "Great Northern Tunnel - Completed in 1905, this one mile long railroad tunnel provided access to the new passenger depot and the expanded freight yards south of King Street. The tunnel was built at the suggestion of city engineer R. H. Thomson to relieve growing street congestion in downtown Seattle."

Freight and passenger trains use the tunnel, including Amtrak service to Chicago (the Empire Builder) and Vancouver, B.C. (Cascades), and Sound Transit's Seattle–Everett Sounder commuter rail service.
