Waipoua Forest is a forest, on the west coast of the Northland Region of New Zealand's North Island. It preserves some of the best examples of kauri forest remaining in New Zealand. It is notable for having two of the largest living kauri trees, Tāne Mahuta and Te Matua Ngahere.
The forest was declared a sanctuary in 1952. A community-based volunteer organisation, the Waipoua Forest Trust, helps maintain the forest. The sanctuary is bordered to the south by the 350 hectares Professor W.R McGregor Reserve, named after W. R. McGregor.
