Copley Square, numita asa dupa pictorul John Singleton Copley, este o piata publica din Boston. Piata este remarcabila pentru numarul si varietatea lucrarilor importante de arhitectura care au fost construite acolo: Old South Church (1873), construita de Charles Amos Cummings si Willard Sears T. in stil venetian gotic; Trinity Church (1877), construita in stil romanic si considerata de HH Richardson un tur de forta; Boston Public Library (1895), construita de Charles McKim Follen si care include opere de arta semnate de John Singer Sargent, Edwin Abbey Austin, Daniel Chester si altii; Fairmont Copley Plaza Hotel (1912) construit de Henry Janeway Hardenbergh in stil Beaux-Arts; John Hancock Tower - cea mai inalta cladire din New England.
