Horahora Domain is a freedom campsite managed by Waipa District Council, situated near Lake Kārapiro in the Waikato region of New Zealand's North Island. It is accessed via Maungatautari Road, Cambridge.

The site accommodates up to 30 campers per night, with a fee of $10 per use. Contained camping is permitted for up to two consecutive nights, while conventional overnight camping is not allowed on the lakeside reserves.

The area draws visitors for its water-based activities on the lake, and reviewers note it can be lively during the day but quieter in the evenings.
