Historic Sites and Monuments Board of Canada

National Historic Sites of Canada (French: Lieux historiques nationaux du Canada) are places that have been designated by the federal Minister of the Environment on the advice of the Historic Sites and Monuments Board of Canada (HSMBC), as being of national historic significance.Parks Canada, a federal agency, manages the National Historic Sites program. As of 2016, there are 976 National Historic Sites, 171 of which are administered by Parks Canada; the remainder are administered and/or owned by other levels of government or private entities. The sites are located across all ten provinces and three territories, with two sites located in France (the Beaumont-Hamel Newfoundland Memorial and Canadian National Vimy Memorial).

There are related federal designations for National Historic Persons and National Historic Events. Sites, Events, and Persons are each typically marked by a federal plaque, but the markers do not indicate which designation a subject has been given. The Rideau Canal is a National Historic Site, while the Welland Canal is a National Historic Event.

Emerging Canadian nationalist sentiment in the late 19th century and early 20th century led to an increased interest in preserving Canada's historic sites. There were galvanizing precedents in other countries. With the support of notables such as Victor Hugo and Eugène Viollet-le-Duc, the Commission des monuments historique was created in France in 1837; it published its first list of designated sites, containing 934 entries, in 1840. In the United Kingdom, the National Trust for Places of Historic Interest or Natural Beauty was created in 1894 to protect that country's historic and natural heritage. While there was no National Park Service in the United States until 1916, battlefields of the Civil War were designated and managed by the War Department: Chickamauga and Chattanooga (created 1890), Antietam (1890), Shiloh (1894), Gettysburg (1895), Vicksburg (1899), and Chalmette (1907).
