Mount Turner is a mountain in the Otago region of New Zealand.
Mount Turner is located northwest of the community of Makarora and is set in Mount Aspiring National Park on South Island. It is part of the West Wanaka Mountains which are part of the Southern Alps. Precipitation runoff from the mountain drains to the Wilkin River and the Makarora River. Topographic relief is significant as the summit rises above Siberia Valley in two kilometres, and above the Wilkin Valley in three kilometres. The nearest higher peak is Mount Awful, eight kilometres to the north. The first ascent of the summit was made in January 1953 by D. Ball, L.W. Bruce, A.R. Craven, and M. McGuire.
Based on the Köppen climate classification, Mount Turner is located in a marine west coast (Cfb) climate zone with a subpolar oceanic climate (Cfc) at the summit. Prevailing westerly winds blow moist air from the Tasman Sea onto the mountains, where the air is forced upward by the mountains (orographic lift), causing moisture to drop in the form of rain or snow. This climate supports a small unnamed glacier on the south slope. The months of December through February offer the most favourable weather for viewing or climbing this peak.
