Moraine Lake is a glacially-fed lake in Banff National Park, 14 kilometres outside the Village of Lake Louise, Alberta, Canada. It is situated in the Valley of the Ten Peaks, at an elevation of 1,885 m.

The lake, being glacially fed, does not reach its crest until mid to late June. When it is full, it reflects a distinct shade of blue. The color is due to the refraction of light off the rock flour deposited in the lake on a continual basis.

The area around the lake has several walking/hiking trails which are, from time to time, restricted because of grizzly bear activity. Parks Canada provides updated trail conditions and/or restrictions.

The easiest of the hiking trails is the one most commonly taken by tourists. The Rockpile Trail along the actual moraine is approximately 300 metres long, with an elevation change of 24 metres. The view of the lake from the top of the rock pile is one of the most photographed locations in all of Canada. That view of the mountains behind the lake in Valley of the Ten Peaks.


Along the same trailhead, the Consolation Lakes trail starts, which is approximately 3 kilometres long, with an elevation change of 90 metres. Upon reaching Consolation Lakes hikers may continue along to the upper lake, which is not visible from the end of the lower lake. There is, however, no clearly marked trail, and can often be a scramble over large rocky areas.

Near the canoe docks of Moraine Lake Lodge there is another trailhead. This trailhead is the start of two trails, one of which branches out into four different trails - so there are in total, five trails starting at that trailhead (Moraine Lake Lakeshore Trail, Eiffel Lake, Wenkchemna Pass, Larch Valley, and Sentinel Pass).
