The Downtown Westerly U.S. Post Office is a historic post office building at High and Broad Streets in Westerly, Washington County, Rhode Island. The building was designed in the Classical Revival style, in 1913 by architect James Knox Taylor. The single-story building features a broad curving facade with eight fluted Doric columns of Vermont marble, flanked by wide piers. The interior lobby space retains many original features, including terrazzo and marble flooring, and a coffered ceiling with decorative moulding.
The building was added to the National Register of Historic Places in 1971.
