Our Mission

The Long Island Museum is dedicated to inspiring people of all ages with an understanding and enjoyment of American art, history and carriages as expressed through the heritage of Long Island and its diverse communities.


The museum has been accredited by the American Association of Museums since 1973 for excellence in exhibitions, programs and collection care. In 2006 the museum joined a small group of institutions nationwide as a Smithsonian Affiliate.
