List of National Historic Landmarks in Maryland

Maryland State House , Annapolis .

The list of National Historic Landmarks in Maryland lists the historical objects and places that are classified as National Historic Landmarks (NHL) in the American state of Maryland and are under the supervision of the National Park Service (NPS), an agency of the US Department of the Interior . These landmarks meet special criteria with regard to their national importance that set them apart from the set of other cultural monuments on the US National Register of Historic Places (NRHP).

This list also includes other Maryland properties that have nationwide historical significance: National Historic Sites , National Historical Parks , National Memorials, and some other entities are areas, landmarks, or memorials in the United States that are not recognized by the Department of the Interior awarded directly by orders of Congress or the President . Such historical monuments are usually also under the protection of the National Park Service, but they were usually not declared in addition to the NHL if the protection status was granted before the introduction of the Landmarks program in 1960. The objects listed in Maryland as national monuments of this kind are listed by the National Park Service in the appendix of the NHL list for Maryland.

Finally, this list also includes those monuments in Maryland that have previously been deprived of an NHL award.
