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.

Who We Are: The Long Island Museum is Long Island’s largest privately supported museum, and is accredited by the American Association of Museums for excellence in exhibitions and programs.  In 2006 the Long Island Museum joined a small group of cultural institutions nationwide as a Smithsonian Affiliate.

Our Collections: The museum’s permanent collection numbers over 40,000 items dating from the late 1700s to the present, including American artifacts of everyday life, works of art and nearly 200 historic carriages.  A selection of items from the museum collections is now available for research.
