The Arrowsmith Range is a mountain range in the South Island of New Zealand. The range runs from southwest to northeast, parallel to the main ranges of the Southern Alps / Kā Tiritiri o te Moana. At the northeastern end, the range terminates at Jagged Peak (2,706 metres (8,878 ft)), whence a ridge connects to the Jollie Range. The lower Potts Range is a continuation at the southwestern end of the range. The highest point on the range is Mount Arrowsmith (2,781 metres (9,124 ft)).^[1]

It is believed that the range was named in honour of John Arrowsmith, the 19th century British cartographer.^[2]

Named peaks from northwest to southeast^[1]

The northwest side of the range is drained by the Lawrence River, a tributary of the Rangitata River, and the southeast side by the Ashburton River South Branch / Hakatere and the Cameron River which flows to Lake Heron.

Although the peaks do not have permanent ice or snow, there are a number of permanent snowfields and glaciers on the range:

• Jagged Glacier
• Douglas Glacier
• Cameron Glacier
• South Cameron Glacier
• Ashburton Glacier
