Lake Temiskaming is a large freshwater lake on the provincial border between Ontario and Quebec, Canada. The lake, which forms part of the Ottawa River, is 110 kilometres in length and covers an area of almost 295 km2.

There are several islands on the lake, notably Mann and du Collège Islands.

The name is from the Algonquin Temikami or Temikaming, meaning "deep waters".

The lake and surrounding area are popular for outdoor recreation. 

There are 30 species of fish in Lake Temiskaming, the best known are northern pike, sturgeon, lake trout, walleye, smallmouth bass, bullhead, carp, ling, perch and whitefish.

The lake was shaped during the last ice age when glaciers carved into the rock. It is also the remnants of a huge basin called Lake Ojibway-Barlow, which existed about 9,500 years ago.
