The Banggai Archipelago (Indonesian: Kepulauan Banggai) is a group of islands, which are located at the far eastern end of Central Sulawesi, Indonesia. The archipelago is surrounded by the Banda Sea's Gulf of Tolo (Teluk Tolo), and the Molucca Sea. The Peleng Straits (Selat Peleng) separate it from mainland Sulawesi.
