Banggai Islands Regency
The Banggai Archipelago is a group of islands located at the far eastern end of Central Sulawesi, Indonesia. It makes up a regency of Central Sulawesi Province of Indonesia, created on 4 October 1999 by splitting the existing Banggai Regency into a residual Banggai Regency situated on the mainland of Sulawesi and a new Banggai Islands Regency then comprising the entire archipelago. On 14 December 2012 a splitting of the Banggai Islands archipelago took place with the removal of the more southerly seven districts from the 13-year-old regency to form a separate Banggai Laut Regency.
The reduced Banggai Islands Regency thus consists almost entirely of the main island of Peleng, together with various small offshore islands, of which the largest is Bangkalan Island off the north coast of Peleng. It covers an area of 2,488.79 km2 and had a population of 109,384 at the 2010 census and 120,142 at the 2020 census; the official population estimate as at mid 2024 was 130,008. The archipelago is surrounded by the Banda Sea's Gulf of Tolo, and the Molucca Sea. The Peleng Straits separate Peleng from the mainland of Sulawesi.
