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]
