Waihi Gorge Campsite is a Department of Conservation campground situated on the banks of the Waihī River, about 14 kilometres northwest of Geraldine in Canterbury's South Island.

The site is set among kahikatea, mataī, and lowland tōtara forest, and is reached via a gravel road off Waihī Gorge Road. The campground offers 40 non-powered and tent sites and requires advance bookings.

Reviewers consistently praise the clear, swimmable river, mountain views, and well-maintained flush toilets.

The site can be prone to flooding in severe weather, and campers are advised to avoid pitching near the riverbank or in the lower section during such conditions. Dogs are not permitted.
