Arthur's Pass is a mountain pass in the Southern Alps of the South Island of New Zealand. The pass sits 920 metres or 3,020 feet above sea level and marks part of the boundary between the West Coast and Canterbury regions. Located 140 km from Christchurch and 95 km from Greymouth, the pass comprises part of a saddle between the valleys of the Ōtira River and of the Bealey River. Arthur's Pass lies on the border of the Selwyn and Westland districts.

The Southern Alps are a mountain range extending along much of the length of New Zealand's South Island, reaching its greatest elevations near the range's western side. The name "Southern Alps" generally refers to the entire range, although separate names are given to many of the smaller ranges that form part of it.
