Ice Peak is the prominent south peak of Mount Edziza in Cassiar Land District of northwestern British Columbia, Canada. It has an elevation of 2,500 metres (8,200 feet) and protrudes through Mount Edziza's ice cap, which is roughly 70 square kilometres (27 square miles) in area. The peak is a pyramid-shaped horn formed by glacial erosion and is completely flanked by steep-walled, active cirques. Tencho Glacier on the southern flank is the largest outlet glacier of Mount Edziza's ice cap. The summit of Ice Peak is about 280 m (920 ft) lower than that of Mount Edziza, but it still rises well above the general level of the Big Raven Plateau. Ice Peak and the surrounding area are in Mount Edziza Provincial Park, which also includes the Spectrum Range to the south.

Ice Peak is the remains of an approximately 1-million-year-old stratovolcano whose original eastern flank has been almost completely destroyed by erosion. Four cirques on the eroded eastern flank have exposed the internal structure of the stratovolcano whereas the southern and western flanks are approximal to those of the original volcano. The northern flank is buried under the younger and higher stratovolcano of Mount Edziza. On the southwestern flank is the Snowshoe Lava Field, which issued from at least 12 vents mostly near the terminus of outlet glaciers in the last 20,000 years. A diverse assemblage of volcanic rocks comprises the Ice Peak stratovolcano and are subdivided into three geological formations with varying ages.
