The Peter C. DuBois House is located on Slocum Road in the Dutchess Junction neighborhood of the city of Beacon, New York, United States. It was one of the last significant Greek Revival buildings in the Hudson Valley. In the 20th century, it would be reused as a sanatorium and altered with the addition of a third story. Today it is once again a dwelling. In 2004 it was added to the National Register of Historic Places.
