Lake Chemong, or Chemong Lake, (pronounced "shi-MONG, from the anisnaabemowin gchi-maang, meaning "big lake")" is a lake 8 km NW of Peterborough, Ontario near the town of Bridgenorth. The lake extends from near Fowlers Corners north to near Curve Lake. Lake Chemong has a length of 14 km and a width of 1 km.

Communities along and near the lakeshore include Bridgenorth, Selwyn on the east, and Ennismore on the west. There is a causeway which crosses the lake, connecting Bridgenorth and Ennismore by road. This causeway is called the James A. Gifford Causeway.

Chemong Lake is part of a tri-lake water system consisting of Chemong Lake, Buckhorn Lake, and Pigeon Lake. The tri-lake area is host to several popular fishing tournaments throughout the open fishing season. The most common game fish in the lake are smallmouth bass, largemouth bass, walleye, yellow perch, Carp, Muskellunge as well as a number of Panfish. Commercial and recreational fishing has caused the introduction of Zebra mussels, which change the ecosystem by filtering the water and making it clearer. Some fish, such as Walleye, dislike the clear water and have become less abundant.
