The Outer Island lighthouse is a lighthouse located on the northern tip of Outer Island, one of the Apostle Islands, in Lake Superior in Ashland County, Wisconsin, near the city of Bayfield.
The light was designed by United States Lighthouse Board Eleventh District Chief Engineer Orlando Poe and constructed under the supervision of his successor, Godfrey Weitzel.
Currently owned by the National Park Service and part of the Apostle Islands National Lakeshore, it was added to the National Register of Historic Places in 1977, part of reference number 77000145. It is listed in the Library of Congress Historic American Buildings Survey, WI-318. The lighthouse is attached to a two-story, red brick keeper's quarters.
