Lewis Pass is a mountain pass at around 900m elevation, in the South Island of New Zealand. The northernmost of the three main passes across the Southern Alps, it is higher than the Haast Pass and slightly lower than Arthur’s Pass. It provides the route between north Canterbury and the West Coast and passes through extensive unmodified beech forest.

The pass is the saddle between the valleys of the Maruia River to the northwest and the Lewis River to the southeast. The saddle is close to the Maruia Springs hot spa.

The area around Lewis Pass is protected as a national reserve. There are a number of tramping routes in the Lewis Pass area, including the St James Walkway. Access this short Alpine Nature Walk loop walk around an alpine wetland and tarn from a carpark near the saddle.
