The Rhode Island Historical Preservation and Heritage Commission, often called RIHPHC, is an agency run by the state of Rhode Island that aims to preserve the state's history and heritage.

The commission works statewide to protect and upkeep historical buildings, districts, archæological sites and structures.

It also has the role of establishing programs designed to record and celebrate the state's culture and heritage.

RIHPHC has also published a series of publications on the history of each of Rhode Island's thirty-nine communities and with a list of important historical places located in each.

Among its former chairs is historical preservationist Antoinette Downing, who held that post for more than three decades beginning in 1968.
