List of National Historic Landmarks in Maryland

This is a List of National Historic Landmarks in Maryland. There are currently 76 National Historic Landmarks (NHLs) in Maryland. Also included are short lists of former NHLs and of other historic sites of national importance administered by the National Park Service.

Historic areas of the NPS in Maryland

National Historical Parks, some National Monuments, and certain other areas listed in the National Park system are historic landmarks of national importance that are highly protected already, often before the inauguration of the NHL program in 1960, and are then often not also named NHLs per se. The National Park Service lists these together with the NHLs in the state.

The Clara Barton National Historic Site, Monocacy National Battlefield and Thomas Stone National Historic Site are also NHLs and are listed above (with the latter under its alternative name, Habre de Venture).
