McKenzie Lake (French: lac McKenzie) is a lake in geographic Speight Township in the Unorganized West Part[4][5] of Timiskaming District in Northeastern Ontario, Canada.

[1][2][6][7][4] It is part of the Saint Lawrence River drainage basin, and is about 20 kilometres (12 mi) southwest of the community of Kenabeek.

[2][6] The lake has two unnamed inflows: one at the south, arriving from Harebell Lake, and one at the west.

The primary outflow is an unnamed creek at the north which flows via Spray Creek, Spring Creek, the Montreal River and the Ottawa River to the Saint Lawrence River.
