Purakaunui Bay Campsite is a DOC conservation campsite on the Catlins coast in the Otago region of New Zealand's South Island, roughly 17 kilometres south of Owaka. It sits directly on the coast and is suitable for tents, campervans, and caravans.

The setting is dramatic, with striking cliff faces, a grassy camping area, resident seals, and a surf beach to the south. Cosgrove Island wildlife refuge lies just offshore, and the well-known Purakaunui Falls are a short drive away.

Bookings are required and must be made online through DOC before arrival; there are no designated individual sites, so campers find their own space on arrival. Fires are permitted only in designated fireplaces and subject to any active fire ban.

Access is via SH1 at Balcutha, heading south past Owaka to the Ratanui turnoff, then along Purakaunui Falls Road, Long Point Road, and finally Purakaunui Bay Road to the end. The final stretch is narrow and unsealed, so drivers should proceed with care.
