The Douglas Ranges are a subrange of the Pacific Ranges of the Coast Mountains of the Canadian province of British Columbia, about 70 km east of downtown Vancouver, north of the Fraser River and between the valleys of Stave and Harrison Lakes. They are approximately 4900 km² (1900 sq mi) in area. Their highest peak is Mount Robertson 2252 m (7388 ft), at the northwest limit of the range. The southern abutment of the Douglas Ranges is over 5000' above the Fraser River between Dewdney and the Harrison River, which flows along the southeast flank of the range.
