The Chilton Club is a private social club established in 1910, located in the Back Bay area of Boston, Massachusetts. Founded by Pauline Revere Thayer, the club was intended in part as a counterpoint to the Mayflower Club. The club was named after Mary Chilton because she had been the first woman to step out of the Mayflower. The club occupies a large red brick building on Commonwealth Avenue, designed in 1870 by architect "Henry Richards of the firm of Ware and Van Brunt."
