Mount Chief Pascall is a mountain summit located in the Joffre Group of the Lillooet Ranges, in southwestern British Columbia, Canada. It is situated east of Pemberton, southwest of Duffy Lake, and within Nlháxten/Cerise Creek Conservancy. Cayoosh Pass lies immediately northwest of the mountain, with Cayoosh Mountain on the opposite side of the pass. Its nearest higher peak is Joffre Peak, to the south, and Mount Rohr rises to the northeast. The mountain's name was submitted by Karl Ricker of the Alpine Club of Canada to honor Chief Bill Pascall, an early leader of the Lillooet Band. The name was officially adopted on January 23, 1979, by the Geographical Names Board of Canada. Precipitation runoff from the peak drains into tributaries of Cayoosh Creek.
