Champ, or Champie, or Champy[1], is the name given to a reputed lake monster living in Lake Champlain, a natural freshwater lake in North America, partially situated across the U.S.-Canada border in the Canadian province of Quebec and partially situated across the Vermont-New York border.[2] While there is no scientific evidence for the cryptid's existence, there have been over 300 reported sightings.[3] The legend of the monster is considered a draw for tourism in the Burlington, Vermont and Plattsburgh, New York areas. Like the Loch Ness Monster, while most regard Champ as legend, others have speculated it is possible such a creature does live deep in the lake, possibly a relative of the plesiosaur, an extinct group of aquatic reptiles

Two Native American tribes living in the area near Lake Champlain, the Iroquois and the Abenaki, had legends about such a creature. The Abenaki called the creature "Tatoskok".[6][7][8]
