The Banda Islands are a volcanic group of ten small volcanic islands in the Banda Sea, about 140 km (87 mi) south of Seram Island and about 2,000 km (1,243 mi) east of Java, and constitute an administrative district (kecamatan) within the Central Maluku Regency in the Indonesian province of Maluku. The islands rise out of 4-to-6-kilometre deep ocean and have a total land area of approximately 172 square kilometres (66 sq mi). They had a population of 18,544 at the 2010 Census and 20,924 at the 2020 Census; the official estimate as at mid 2023 was 21,902. Until the mid-19th century the Banda Islands were the world's only source of the spices nutmeg and mace, produced from the nutmeg tree. The islands are also popular destinations for scuba diving and snorkeling. The main town and administrative centre is Banda Neira, located on the island of the same name.

The Banda Sea is one of four seas that surround the Maluku Islands of Indonesia, connected to the Pacific Ocean, but surrounded by hundreds of islands, including Timor, as well as the Halmahera and Ceram Seas. It is about 1000 km (600 mi) east to west, and about 500 km (300 mi) north to south.
