The John Waterman Arnold House is an historic house at 11 Roger Williams Avenue in Warwick, Rhode Island. Built sometime in the late 18th century, it is a two-story five-bay wood-frame structure with a central chimney, and a two-story ell extending to the rear. It distinctively has a fireplace in its cellar, suggesting this area was once used as a kitchen. The main entrance has 19th-century Greek Revival treatment. The house was listed on the National Register of Historic Places in 1971. The property is now owned by the Warwick Historical Society, and is open to the public.
