Lewis Pass is the northernmost of the three main mountain passes through the Southern Alps in the South Island of New Zealand. With an elevation of 907 metres, it is slightly lower than Arthur's Pass and higher than Haast Pass. The pass is the saddle between the valleys of the Maruia River to the northwest in the West Coast Region and the Lewis River to the southeast in north Canterbury. The small spa of Maruia Springs is close to the saddle, on the West Coast side.
