Manitowoc Breakwater Light is a Lake Michigan lighthouse near Manitowoc, Wisconsin, at the end of the north pier forming the city’s harbor. It marks the outer edge of the harbor entrance and serves as the principal light on that side of the breakwater. It stood opposite a smaller navigational beacon on the south pier that complemented it at the harbor entrance. That south beacon was torn loose and swept into the lake on January 7, 2019, during heavy waves and lakeshore flooding caused by strong winds.
