Mount Weed is a mountain summit located in the Mistaya River valley of Banff National Park, in the Canadian Rockies of Alberta, Canada. Mount Weed is situated at the confluence of Silverhorn Creek and Mistaya River, 3.5 kilometres southwest of Mount Noyes, 4.5 km east of Mistaya Lake, and 14 km north of Bow Lake. Its nearest higher peak is Mount Patterson, to the southwest. Patterson stands directly across the Mistaya River valley from Weed, and both are prominent features seen from the Icefields Parkway.
