Whatamango Bay Campsite is a Department of Conservation (DOC) campground situated beside the beach in the Queen Charlotte Sound/Tōtaranui area of the Marlborough region on New Zealand's South Island.

The site offers up to 50 non-powered tent sites spread across a large grassed area, with many spots close to the water's edge and some sheltered by trees and shrubs. Facilities are basic, including a toilet block and water supply (treatment recommended).

Fires are not permitted at any time, and dogs are not allowed. Bookings are required and no walk-in spaces are held. The campground is a popular stopover for travellers catching early or late Picton ferry sailings, sitting roughly 15 minutes from the terminal.

Its quiet, waterfront setting makes it well suited for fishing, exploring, or simply relaxing by the sound.
