The Amarapura Nikaya was a Sri Lankan monastic fraternity founded in 1800. It is named after the city of Amarapura, Burma, the capital of the Konbaung dynasty of Burma at that time. Amarapura Nikaya monks are Theravada Buddhists. On 16 August 2019, the Amarapura and Ramanna Nikaya were unified as the Amarapura–Rāmañña Nikāya, making it the largest Buddhist fraternity in Sri Lanka.

Amarapura is a former capital of Myanmar, and now a township of Mandalay city. Amarapura is bounded by the Irrawaddy river in the west, Chanmyathazi Township in the north, and the ancient capital site of Ava (Inwa) in the south. It was the capital of Myanmar twice during the Konbaung period before finally being supplanted by Mandalay 11 kilometres (6.8 mi) north in 1859. It is historically referred to as Taungmyo in relation to Mandalay. Amarapura today is part of Mandalay, as a result of urban sprawl. The township is known today for its traditional silk and cotton weaving, and bronze casting. It is a popular tourist day-trip destination from Mandalay.
