Nydia Campsite is a DOC-managed backcountry campsite situated in a sheltered, scenic bay within the Pelorus Sound/Te Hoiere area of the Marlborough region, New Zealand.

It sits along the popular Nydia Track, serving as a midpoint stop between Duncan Bay and Nydia Lodge via Nydia Saddle. The surrounding area offers opportunities for walking, biking, and boating.

The campsite has eight unpowered sites and is well set up for backcountry travellers, with a cooking platform, water tap, and long-drop toilet. Tap water is sourced from a nearby creek and may be limited during dry summers, so water conservation is encouraged.

Fires are not permitted at any time. Bookings are required, and a DOC Campsite Pass is accepted.
