The Wheelwright Block is a historic commercial building at 34 Hammond Street in Bangor, Maine. Built in 1859, it occupies a central position in the city's West Market Square at the junction of Main, Broad, and Hammond Streets. It was the state's first commercial Second Empire building, and notably survived both Bangor's devastating 1911 fire, and its major urban renewal programs of the late 1960s. It was listed on the National Register of Historic Places in 1974.
