The Neal Dow House, also known as Gen. Neal Dow House, is an historic house at 714 Congress Street in Portland, Maine. It was built in 1829 for noted politician and prohibitionist Neal Dow (1804-1897), and was designated a National Historic Landmark for that association. Dow was the author of the first prohibition law, passed by the Maine legislature in 1851 (and giving such laws the epithet "Maine law"), and was a tireless internationally-known activist in the temperance movement. Dow's house was a center of activism in his lifetime, and is now the headquarters of the Maine chapter of the Women's Christian Temperance Union.
