Floe Lake is a lake in Kootenay National Park, British Columbia, Canada. The lake is accessible by a 10.7 km hiking trail that leaves from a marked trailhead on highway 93 or the Rockwall Trail.

There is a backcountry campground at the lake as well as a Warden's cabin staffed by Parks Canada.

An image of Floe Lake appears on the wall of the International Arrivals at Customs Canada in the Calgary International Airport.
