Phyllis Beatrice Munday CM (née James; 24 September 1894 – 11 April 1990) was a Canadian mountaineer, explorer, naturalist and humanitarian.

The family departed Ceylon in 1901, and moved to England and Manitoba before settling on the western shore of Kootenay Lake in 1903.

Phyllis and her sister Betty enjoyed their opportunities for exploration in the Kootenays, but Frank disliked the instability of the mining business, and in 1907 the family sought to emigrate to New Zealand.

From 1923 to 1926 the Mundays lived in a tent, and then a cabin on Grouse Mountain where Don worked cutting a trail from Lonsdale Avenue in North Vancouver, British Columbia to the summit, while Phyllis ran the Alpine Lodge, serving hot drinks and meals to hikers.

[1] In the words of Don Munday: "The compass showed the alluring peak stood along a line passing a little east of Bute Inlet and perhaps 150 miles away, where blank spaces on the map left ample room for many nameless mountains.
