Mount Pelops is a mountain summit located in the Tantalus Range, in Tantalus Provincial Park, in southwestern British Columbia, Canada. It is situated northwest of Squamish, and southeast of Mount Tantalus, which is the highest peak in the Tantalus Range. Its nearest higher peak is Mount Niobe, to the northwest, and Omega Mountain lies to the east. Precipitation runoff from the peak drains into tributaries of the Squamish River. The first ascent of the mountain was made in 1916 by Tom Fyles and his brother, John Fyles. The mountain was named for Pelops, brother of Niobe and son of Tantalus according to Greek mythology, with several peaks in the Tantalus Range being named for family members of Tantalus. The mountain's name was officially adopted on June 6, 1957, by the Geographical Names Board of Canada.
