Back Bay station is an intermodal passenger station in Boston, Massachusetts. It is located just south of Copley Square in Boston's Back Bay and South End neighborhoods. It serves MBTA Commuter Rail and MBTA subway routes, and also serves as a secondary Amtrak intercity rail station for Boston. The present building, designed by Kallmann McKinnell & Wood, opened in 1987. It replaced the New Haven Railroad's older Back Bay station – which opened in 1928 as a replacement for an 1899-built station – as well as the New York Central's Huntington Avenue and Trinity Place stations which had been demolished in 1964.

Copley Square, is a public square in Boston's Back Bay neighborhood, bounded by Boylston Street, Clarendon Street, St. James Avenue, and Dartmouth Street. The square is named for painter John Singleton Copley. Prior to 1883 it was known as Art Square due to its many cultural institutions, some of which remain today.
