Lake Māhinapua Campsite sits within Māhinapua Scenic Reserve on the West Coast of New Zealand's South Island, about 10 km south of Hokitika. Campers set up among forest surroundings directly beside the lake, making it a popular overnight and day stop.

Water sports on the lake are a draw, and short walking tracks — including the Jum Michel Walk and Swimmers Beach Walk — thread through the surrounding bush. The campsite is managed by the Department of Conservation and requires advance booking.

It operates on a pack-in/pack-out basis, with no rubbish or recycling facilities on site. Access is via Lake Māhinapua Access Road off SH6, opposite the hotel, with the campground at road's end roughly 300 metres in.
