United States Post Office–Naugatuck Main

The U.S. Post Office-Naugatuck Main, also known as Naugatuck Main Post Office, is a historic post office building at Church and Cedar Streets in Naugatuck, Connecticut. It is a brick building, trimmed with cast terra cotta and marble, and a hipped red tile roof. It was designed by James A. Wetmore and completed in 1916. It is one of the first post office buildings built under the authority of the Public Buildings Act of 1913, and makes a harmonious contribution to the adjacent cluster of civic buildings designed by McKim, Meade & White.

The building was listed on the National Register of Historic Places in 1986.
