Alpaca Peak is a 2,083-metre (6,834-foot) granitic mountain located in the North Cascades of southwestern British Columbia, Canada. It is situated 8 km (5 mi) northwest of Coquihalla Summit, and 1.47 km (1 mi) southwest of Vicuna Peak, its nearest higher peak. Precipitation runoff from the peak drains west into headwaters of the East Anderson River, or east into headwaters of the Coldwater River. The mountain was named for the alpaca, as part of the ungulate names theme for several other nearby peaks that were submitted by Philip Kubik of the 1965 first ascent party. The mountain's name was officially adopted on March 23, 1976, by the Geographical Names Board of Canada.
