Lake Champlain (/ʃæmˈpleɪn/ sham-PLAYN; French: Lac Champlain, pronounced [lak ʃɑ̃plɛ̃] ) is a large natural freshwater lake in North America. With a length of 107 mi (172 km) and surface area over 500 sq mi (1,295 km), it lies mostly between the U.S. states of New York and Vermont, but also extends north into the Canadian province of Quebec.
The cities of Burlington, Vermont, and Plattsburgh, New York, are the largest settlements on the lake, and towards the south lies the historic Fort Ticonderoga in New York. The Quebec portion is in the regional county municipalities of Le Haut-Richelieu and Brome-Missisquoi. There are a number of islands in the lake; the largest include Grand Isle, Isle La Motte and North Hero: all part of Grand Isle County, Vermont. Because of Lake Champlain's connections both to the St. Lawrence Seaway via the Richelieu River, and to the Hudson River via the Champlain Canal, Lake Champlain is sometimes referred to as "The Sixth Great Lake".
