The Stannard Rock Light is a lighthouse located on a reef that was the most serious hazard to navigation on Lake Superior. The exposed crib of the Stannard Rock Light is rated as one of the top ten engineering feats in the United States. It is 24 miles (39 km) from the nearest land, making it the most distant (from shore) lighthouse in the United States. It was one of the "stag stations", manned only by men, and had the nickname "The Loneliest Place in the World".

The lighthouse was automated in 1962 and the United States Coast Guard still maintains it as an active aid to navigation. It is closed to the public and can only be viewed by boat or airplane. It was listed on the National Register of Historic Places in 1971.
