List of islands of Indonesia
The exact number of islands comprising Indonesia varies among definitions and sources. According to a geospatial survey conducted between 2007 and 2010 by Badan Koordinasi Survei dan Pemetaan Nasional (Bakorsurtanal), the National Coordinating Agency for Survey and Mapping, Indonesia has 13,466 islands. However, according to earlier survey in 2002 by National Institute of Aeronautics and Space (LAPAN), the Indonesian archipelago has 18,307 islands, and according to the CIA "World Factbook", there are 17,508 islands.

According to estimates made by the government of Indonesia 8,844 islands have been named, with 922 of those permanently inhabited.The following islands are listed by province:
