Elaine Bay Campsite is a DOC Standard campsite set on the waterfront at Elaine Bay Recreation Reserve in the Marlborough Sounds, New Zealand.

Situated roughly halfway along the Croisilles–French Pass Road, it sits within the Pelorus Sound/Te Hoiere and Kenepuru Sound area and is reached via a sealed but narrow, winding road off SH 6 north of Rai Valley.

The campsite offers up to 20 unpowered tent sites and serves as a practical base for exploring the outer Sounds by boat, fishing from the wharf, and enjoying watersports.

It also sits near the northern end of the Archers walking track, which winds through native bush to Tennyson Inlet, and is accessible to mountain bikers. Note that fires are not permitted at any time.

Reviewers highlight the beautiful waterfront setting, though the site can be exposed to wind.
