The Acadian Landing Site, also known as the Acadian Cross Historic Shrine, is a site historically significant to the French-American Acadian population of far northern Maine. Located on the southern bank of the Saint John River east of Madawaska and marked by a large marble cross, it is the site traditionally recorded as the landing point of the first Acadians to settle this region of the upper Saint John River. The site was listed on the National Register of Historic Places in 1973.
