The Fogg Building is a historic commercial building at 100–110 Pleasant Street and 6–10 Columbian Street in Weymouth, Massachusetts. The 3-1/2 story masonry building was designed by J. Williams Beal, and built in 1887 for local businessman John Fogg. The Richardsonian Romanesque structure originally housed a performance space and social gathering places in its upper floors; these spaces have been converted to apartments. The building was listed on the National Register of Historic Places in 1983.
