The National Maritime Heritage Foundation (NMHF) is a 501(c)(3) non-profit organization that manages community sailing and maritime education programs in Washington, D.C. In September 2009, the NMHF formally proposed a "National Naval and Maritime Museum" that would be built in Washington, D.C. The NMHF is in no way connected to the Naval Historical Foundation (NHF), the official U.S. Navy-endorsed group that raises private funds in support of the National Museum of the U.S. Navy (U.S. Navy Museum) in Washington, D.C.
