Rotorua (from Māori: Te Rotorua-nui-a-Kahumatamomoe, "The second great lake of Kahumatamomoe") is a city on the southern shores of the lake of the same name, in the Bay of Plenty region of the North Island of New Zealand. The city is the seat of the Rotorua District, a territorial authority encompassing the city and several other nearby towns. Rotorua city has an estimated permanent population of 56,200, with the Rotorua district having a total estimated population of 68,900. The city is in the heart of the North Island, just 60 kilometres (37 mi) south of Tauranga, 80 kilometres (50 mi) north of Taupo, 105 kilometres (65 mi) east of Hamilton, and 230 kilometres (140 mi) southeast of Auckland.
The Rotorua region has 17 lakes. Fishing, waterskiing, swimming and other water activities are popular in summer. The lakes are also used for event venues; Rotorua hosted the 2007 World Waterski Championships and Lake Rotorua was the venue for the World Blind Sailing Championships in March 2009. Lake Rotorua is also used as a departure and landing point for float planes.
The name Rotorua comes from Māori, the full name being Te Rotorua-nui-a-Kahumatamomoe; roto means lake and rua two – Rotorua thus meaning 'Second lake'. Kahumatamomoe was the uncle of the Māori chief Ihenga, the ancestral explorer of the Te Arawa. It was the second major lake the chief discovered, and he dedicated it to his uncle. It is the largest of a multitude found to the northeast of the city, all connected with the Rotorua Caldera and nearby Mount Tarawera. The name can also mean the equally appropriate 'crater lake'.

The area was initially settled by Māori of the Te Arawa iwi. The first European in the area was probably Phillip Tapsell who was trading from the Bay of Plenty coast at Maketu from 1828. He later married into Te Arawa and became highly regarded by them. Missionaries Henry Williams and Thomas Chapman visited in 1831 and Chapman and his wife established a mission at Te Koutu in 1835. This was abandoned within a year but Chapman returned in 1838 and established a second mission at Mokoia Island.
The lakeshore was a prominent site of skirmishes during the New Zealand Wars of the 1860s. A "special town district" was created in the 1883, in order to promote Rotorua's potential as a spa destination. The town was connected to Auckland with the opening of the Rotorua Branch railway and commencement of the Rotorua Express train in 1894, resulting in the rapid growth of the town and tourism from this time forward. Rotorua was established as a borough in 1922 and declared a city in 1962 before becoming a District in 1979.
