The Breakwater is a historic sporting lodge on the Mount Kineo peninsula of Moosehead Lake in central Maine. Built in 1909, it is an architecturally sophisticated example of a sporting lodge, exhibiting Shingle style and Italianate features. It was designed by Howard G. Chamberlain, a New York City architect, with funding from the nearby Mount Kineo Resort and the Moosehead Yacht Club. It was one of the centerpieces of central Maine's most successful summer resort, and was listed on the National Register of Historic Places in 2002.
