Lake Tarawera is the largest of a series of lakes which surround the volcano Mount Tarawera in the North Island of New Zealand. Like the mountain, it lies within the Okataina caldera. It is located 18 kilometres (11 mi) to the east of Rotorua, and 5 kilometres (3.1 mi) to the west of the mountain. The lake's surface area is 39 square kilometres (15 sq mi).
The lake was substantially affected by the eruption of Mount Tarawera on 10 June 1886. The eruption killed over 150 people, and buried the Māori village of Te Wairoa on the southwest shore of the lake.
Also destroyed were the famed Pink and White Terraces. However, in February 2011 a team mapping the lake floor discovered what appeared to be part of the Pink Terraces. The lowest two tiers of the terraces were reportedly found in their original place at 60 metres (200 ft) deep (too deep for scuba diving without special gas gear). Subsequently, a portion of the White Terraces was reportedly rediscovered in June 2011. The announcement of the rediscovery of the White Terraces coincided with the 125th anniversary of the eruption of Mt. Tarawera in 1886. It was thought that the rest of the terraces may be buried in sediment rather than having been destroyed.
Tarawera means "Burnt Spear", named by a visiting hunter who left his bird spears in a hut and on returning the following season found both the spears and hut had been burned down completely.

The main hot water sources are in the southern section of the lake at the Wairua Stream, Hot Water Beach and Te Puha and Tarawera fumaroles. There is also a small geothermal area at Humphrey's Bay, to the south of Lake Okataina. Water varies between 37 °C (99 °F) and 90 °C (194 °F).
