Jackson Bay / Okahu (Māori: Ōkahu)[1] is a gently curving 24-kilometre (15 mi) bay on the southern West Coast of the South Island of New Zealand. It faces the Tasman Sea to the north, and is backed by the Southern Alps. It contains the settlements of Hannahs Clearing, Waiatoto, Neils Beach, and the fishing village of Jackson Bay at its western end. The bay is the southernmost terminus of the West Coast's roads.
