Maine Publicity Bureau Building, historic commercial building at 501 Danforth Street in Portland, Maine, United States

The Maine Publicity Bureau Building is a 1-1/2 story brick building at 501 Danforth Street in Portland, Maine, on the northeast side of a 90-degree bend in the street. Its five-bay side-gable center is flanked by symmetrical single-story front-gable sections, each holding a Palladian-style window group of narrow fixed windows around a central sash topped by a half-round fan. The center section has sash windows with flat keystone lintels, and the recessed double-door entrance is framed by pilasters under a broken segmented pediment.

The building was constructed in 1936 during the Great Depression using federal Works Progress Administration funding to serve as headquarters for the Maine Publicity Bureau founded in 1921. The bureau relocated to Hallowell in 1979, and the building was added to the National Register of Historic Places in 1990.

The building served as the face of Maine's tourism promotion and shows how important travel and visitor economy was to the state in the early 20th century. Travelers could stop here to gather maps, brochures, and guides that introduced them to Maine's attractions.

The building sits on a slight rise along Danforth Street in western Portland, making it visible and easy to locate from the street. Access is convenient for pedestrians exploring the West End Historic District neighborhood.

The building stands on a 90-degree bend in Danforth Street, on a slight rise, but its view of the Fore River is blocked by the raised embankment carrying Commercial Street. The state owned the land and building, leasing them to the Bureau until the headquarters moved to Hallowell in 1979. On July 28, 2025, the cupola was damaged by fire.
