Round Island Passage Light is an automated, unmanned 1948 lighthouse located in the Round Island Channel in the Straits of Mackinac, Michigan. The channel is a branch of Lake Huron.^[6]

History

Round Island Passage Light, built by the United States Coast Guard of concrete and steel in the period immediately following World War II, was one of the last lights to be constructed on the Great Lakes. The light was built at the same time that Round Island Light, an 1898 historically manned lighthouse at the other end of the channel, was deactivated. As of 2009, however, Round Island Light has been relighted as a private aid to navigation, and both lights currently mark the channel.^[7]

On August 7, 2013, the light was listed on the National Register of Historic Places.^[5]
