Tauranga Taupō is a semi-rural area located at the mouth of Tauranga Taupō River, on the southern shores of Lake Taupō in New Zealand's North Island.

The area includes three contiguous settlements: Oruatua, near the mouth of the Tauranga Taupō River. Te Rangiita or Rangiita, and Waitetoko or Waitetoko Beach. These settlements are located southwest to northeast on State Highway 1.

The closest towns are Tūrangi which is 13km south of Te Rangiita and Taupō, which is 37km northwest .

The shores of Lake Taupō were first inhabited by Ngāti Hotu during the fourteenth century. Māori legends speak about explorers Tia and Ngātoro-i-rangi, who competed to claim land along the shores of Lake Taupō and passed through Tauranga Taupō. The children of Ngātoro-i-rangi's descendant Tūwharetoa came to the Taupō District and created the iwi Ngāti Tūwharetoa. A descendant of Tūwharetoa named Te Rangi-ita and his son Tama-mutu became important figures in the iwi around the seventeenth century. They were warrior chiefs who established territories in the Taupō District and established the Ngāti Te Rangi-ita hapū in the Tauranga Taupō area.

Europeans began arriving to the Taupō area in the early nineteenth century. The first road along the south eastern side of the lake was built in 1883. 1924 saw the construction of the Tauranga-Taupō bridge completing the road from Taupō to Tokaanu. This would later become State Highway One.

The local Waitetoko Marae is a marae for the local Ngāti Tūwharetoa hapū of Ngāti Te Rangiita. It includes Te Kapua Whakapipi meeting house.
