The Ashland Harbor Breakwater lighthouse, also known as Ashland Breakwater Lighthouse, is an operational lighthouse located near Ashland in Ashland County, Wisconsin, USA.[9] Located in Chequamegon Bay of Lake Superior, it is owned and managed by the U.S. Coast Guard.[10] It sits at the end of a long and detached breakwater, which creates an artificial harbor.[11]

A lighthouse keeper's quarters and a boathouse, constructed in 1916, are located about 2 miles (3.2 km) from the light. There are additional living quarters on the second and third stories of the lighthouse.[10]
