The Larchmont Historical Society was chartered in 1981 as a not-for-profit educational corporation by the New York State Board of Regents to discover, preserve and disseminate information concerning the natural, social and civic history of Larchmont and to promote the preservation of historical sites and structures.

  The Society maintains an archive; publishes a monthly newsletter; offers regular programs; conducts tours for school children and adults and offers outreach lectures to other groups in the community. It is governed by a voluntary Board of Trustees elected by the members of the Society.
