The Waterton-Glacier International Peace Park is the name of the union of the Glacier National Park in the United States and the Waterton Lakes National Park in Canada. Both parks are declared Biosphere Reserves by UNESCO and their union as a World Heritage Site.

The union of the parks was achieved through the efforts of Rotary International members from Alberta and Montana in 1932. It was the world's first International Peace Park, symbolising peace and friendship between the two countries. To this day, it remains the world's only one set up with that primary purpose, although efforts are under way for a USA-Mexico International Park[1].

See the articles for the two individual parks for more information.
