Kawaweogama Lake is a lake in the James Bay drainage basin in Unorganized Thunder Bay District in northwestern Ontario, Canada, about 35 kilometres (22 mi) east of the community of Savant Lake on Highway 516, 80 kilometres (50 mi) west of Armstrong on Highway 527, and 210 kilometres (130 mi) northwest of Thunder Bay.

[1] Except for the northwestern shore, the lake is encompassed by Brightsand River Provincial Park.

The outlet channel at the north combines with the eastern branch of the Brightsand River arriving as the outlet from McEwan Lake to form the river Allan Water.

The (uninhabited) community of Allanwater Bridge is just beyond the north end of the lake.

The CN mainline also crosses the northern tip of the lake west of Allanwater Bridge.
