Blair Peak is a mountain on the shared border of the West Coast and Canterbury Regions of New Zealand.
Blair Peak is a summit situated on the crest of the Southern Alps in the South Island. Precipitation runoff from the mountain drains north to the Lord River, and south into the headwaters of the Rakaia River. Topographic relief is significant as the summit rises above the Radiant Glacier in one kilometre and above the Cockayne Glacier in one kilometre. The nearest higher neighbour is Malcolm Peak, 3.66 kilometres to the southwest. The mountain's toponym has appeared in publications since 1911.

Based on the Köppen climate classification, Blair Peak is located in a marine west coast (Cfb) climate zone. 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 fall in the form of rain or snow. This climate supports the Radiant Glacier on the northern slope of the peak, Cockayne Glacier on the southeast slope, and the Heim Plateau on the southwest slope. The months of December through February offer the most favourable weather for viewing or climbing this peak.
