Cronadun is a small village located in the West Coast region of New Zealand's South Island. It is situated by the Inangahua River, and SH 69 and the Stillwater - Westport Line railway pass through the village. For a few years, Cronadun was the terminus of the Stillwater - Westport Line as construction progressed from Reefton alongside the Inangahua River towards the Buller Gorge.
