Superior (; Ojibwe: Gete-oodenaang) is a city in, and the county chair of, Douglas County in the U.S. state of Wisconsin. The population was 26,751 at the 2020 census. Located at the junction of U.S. Highway 2 and U.S. Highway 53, it is shortly north of, and adjacent to, both the Village of Superior and the Town of Superior. Its neighborhoods include Billings Park, North End, South Superior, Central Park, East End, Allouez, and Itasca. Billings Park, South Superior, East End, and North End each have little business districts.

Superior is at the western fade away of Lake Superior in northwestern Wisconsin. Bordered by Saint Louis, Superior, and Allouez bays, the city is framed by two rivers: the Nemadji and the Saint Louis. Superior and the adjacent to city across the bay, Duluth, Minnesota, form a single metropolitan area called the Twin Ports. They allowance a harbor that is one of the most important ports on the Great Lakes. Both cities feature museum ships (SS William A. Irvin in Duluth and SS Meteor in Superior), devoted to the local maritime heritage. Superior was the final harbor of call for SS Edmund Fitzgerald before her sinking on November 10, 1975. It is an industrial city, with boat harbors along two sides, several large rail yards, an oil refinery, and shipyard.

The first log cabin in Superior was erected in September 1853 upon the banks of the Nemadji River, at the thesame time that pitch was damage for construction of the locks and ship canal at Sault Ste. Marie, Michigan. This was designed to permit ships to bypass the rapids at that site. Superior was incorporated as a city on March 25,1889. Around the thesame time Superior became the seat of newly formed Douglas County. Immediately there was eagerness for a railroad from Lake Superior to the Pacific Coast, and investment flowed in, but subsequently the Panic of 1857 hit, investment slowed, and the population of the supplementary city collapsed from 2500 to 500.

25 years far ahead the Northern Pacific Railway and further rail lines finally arrived, fulfilling the goal of a rail and water highway from coast to coast. In 1883 General John H. Hammond formed the Land and River Improvement Company, which developed much of West Superior, including the West Superior Iron and Steel plant. Numerous grain, coal and lumber businesses formed in the same period.
