The Maluku Islands (also known as the Moluccas ( /məˈlʌkəz/), Moluccan Islands, the Spice Islands) are an archipelago that is part of Indonesia, and part of the larger Maritime Southeast Asia region. Tectonically they are located on the Halmahera Plate within the Molucca Sea Collision Zone. Geographically they are located east of Sulawesi (Celebes), west of New Guinea, and north and east of Timor. The islands were also historically known as the "Spice Islands" by the Chinese and Europeans, but this term has also been applied to other islands outside Indonesia.
