Mistletoe Bay Campsite is a DOC-managed campground set within the Marlborough Sounds in New Zealand's Queen Charlotte Sound/Tōtaranui area. There is no road access to the site; visitors arrive by boat or water taxi, which adds to its sense of seclusion.

The campground offers around forty non-powered tent and campervan sites along with a shared camp kitchen equipped with stoves, microwaves, fridges, and a log burner.

The site is operated in partnership with Mistletoe Bay Eco Village, a conservation-focused trust that channels commercial revenue toward subsidised school programs.

Guests can explore several short walking tracks on the surrounding peninsula without needing a Queen Charlotte Track Pass.

The sheltered bay is popular for swimming and fishing, kayak and paddleboard hire is available on-site, and the area is known for nighttime phosphorescence near the wharf and glow worms along the driveway.

Wildlife sightings including dolphins, seals, and occasional orca have been reported.
