Nina Bay is a campground on Hinchinbrook Island's Thorsborne Trail in Queensland, situated on the beach within the island's eastern coastal wilderness.

The site offers two distinct camping areas: one in the forest at the edge of the beach, and a second more secluded spot reached via a track between the toilet and the beach, set about three metres above the shoreline. A drop toilet is available on site.

Fresh water can be collected from a creek approximately 200 metres before reaching the campsite, or from the creek at the southern end of the beach. A further creek lies 100 metres north of the upper campsite. Nina Bay is roughly 1.

5 hours walk from Little Ramsay Bay, with Boulder Bay sitting about midway between the two.
