Mount Rohr is a mountain summit located in the Cayoosh Range of the Lillooet Ranges, in southwestern British Columbia, Canada. It is situated east of Pemberton, east of Cayoosh Mountain, and northeast of Joffre Peak, its nearest higher peak. Highway 99 traverses the southern base of the mountain between Cayoosh Pass and the west end of Duffy Lake, while Mount Chief Pascall rises on the opposite (south) side of this highway. Mount Rohr forms the westernmost boundary of Duffey Lake Provincial Park as it also represents the park's highest point . The mountain's name was submitted by Rev. Damasus Payne, a mountaineer, to honor Rev. Victor Sebastian Rohr (1873-1965), who spent 40 years in British Columbia and was a missionary to the First Nations in the region between Skookumchuck and Williams Lake. The name was officially adopted on April 21, 1966, by the Geographical Names Board of Canada. Two established climbing routes are the West Ridge and via Rohr Lake, both of which can be skied in winter. Precipitation runoff from the peak drains north into headwaters of Haylmore Creek, or south into Cayoosh Creek.
