List of the oldest buildings in Rhode Island

This article attempts to list the oldest buildings in the state of Rhode Island in the United States of America, including the oldest houses in Rhode Island and any other surviving structures. Some dates are approximate and based on architectural studies and historical records, other dates are based on dendrochronology All entries should include citation with reference to: architectural features; a report by an architectural historian; or dendrochronology

Very few Rhode Island buildings have been tested yet using dendrochronology (less than a dozen houses as of 2019), and most buildings outside of Aquidneck Island were burned in King Philip's War in the 1670s. The oldest building in Rhode Island tested using dendrochronology was the Clemence-Irons House (1691) in Johnston, although the Lucas–Johnston House in Newport holds some timbers which were felled prior to 1650, but likely reused from an earlier building.
