Rotorua is a city in the Bay of Plenty Region of New Zealand's North Island. It is sited on the southern shores of Lake Rotorua, from which it takes its name. It is the seat of the Rotorua Lakes District, a territorial authority encompassing Rotorua and several other nearby towns. It has an estimated resident population of 58,900, making it the country's 13th largest urban area, and the Bay of Plenty's second-largest urban area behind Tauranga.

The Bay of Plenty Region, often abbreviated to BOP, is a region in the North Island of New Zealand situated around the body of water of the same name. The bay was named by James Cook after he noticed the abundant food supplies at several Māori villages there, in stark contrast to the earlier observations he had made in Poverty Bay.
