Porters Pass (elevation 939 metres) is a mountain pass in the Canterbury region of New Zealand's South Island. It is near Lake Lyndon and is located within Korowai/Torlesse Tussocklands Park. State Highway 73 travels through the pass on its route from Springfield to Cass, and it is the last mountain pass on the route eastwards from Westland to Christchurch. Although Arthur's Pass is better known, Porters Pass is actually a few metres higher, and it affords views of the Canterbury Plains. The pass was named in 1858 by the Porter brothers who were farming nearby.
