The Silverthrone Group, also called the Silverthrone Cluster, is an extensive group of mountains in the Pacific Ranges of British Columbia, Canada. It includes more than 30 named mountains, the highest of which is Silverthrone Mountain with an elevation of . The Silverthrone Group is bounded in the east by the Klinaklini and North Klinaklini rivers, in the south by Knight Inlet, in the west by the Pacific Ocean and in the north by Owikeno Lake, Rivers Inlet and the Sheemahant River. Climbing and explorations of the group began in at least 1900; some of the mountaineers involved in these activities were Don Munday, Phyllis Munday and John Clarke.
This mountain group has been called the Silverthrone Group by the British Columbia Mountaineering Club and the Silverthrone Cluster by the Bivouac Mountain Encyclopedia. Such terms are derived from Silverthrone Mountain, the highest point of the Silverthrone Group whose name has been reported in Canadian Alpine Journal articles as early as 1933. Silverthrone is descriptive of the icy landscape; it may have been coined by Don Munday who carried out the first ascent of Silverthrone Mountain along with his wife Phyllis Munday in 1936.
The Silverthrone Group is wide and covers of the Pacific Ranges of the Coast Mountains. In some places, the Silverthrone Group is occupied by the Ha-Iltzuk Icefield, which covers of the southern Coast Mountains. The eastern boundary of the Silverthrone Group lies west of the Klinaklini and North Klinaklini rivers. To the south, the Silverthrone Group is bounded by Knight Inlet whereas the western boundary is marked by the Pacific Ocean. Bounding the northern end of the Silverthrone Group is Owikeno Lake, Rivers Inlet and the Sheemahant River. The group is west of Mount Waddington, the highest mountain entirely within British Columbia.
