Alderson Lake Camp is a backcountry campsite within Waterton Lakes National Park, Alberta, situated on the far shore of Alderson Lake beneath the dramatic cliffs of Mount Alderson.

It is one of nine designated backcountry campgrounds in the park and is a stop along the Great Divide Trail.

The camp is most commonly reached via the Carthew-Alderson Trail, a difficult 19–20 km route with roughly 900 m of elevation gain, though a more direct approach begins at Cameron Falls in the townsite. Campfires are not permitted at this site.

Reservations can be made through the Parks Canada Reservation Service, and a Wilderness Pass is required for overnight stays.
