Maritime Southeast Asia
Maritime Southeast Asia (as opposed to Mainland Southeast Asia) comprises the countries of Brunei, East Timor, Indonesia, Malaysia (East Malaysia), the Philippines, and Singapore. Maritime Southeast Asia is sometimes also referred to as Island Southeast Asia, Insular Southeast Asia or Oceanic Southeast Asia. The 16th-century term "East Indies" and the later 19th-century term "Malay Archipelago" are also used to refer to Maritime Southeast Asia.

In Indonesia and Malaysia, the Old Javanese term "Nusantara" is also used as a synonym for Maritime Southeast Asia. The term, however, is nationalistic and has shifting boundaries. It usually only encompasses the Malay Peninsula, the Sunda Islands, Maluku, and often Western New Guinea; excluding the Philippines and Papua New Guinea.
Stretching for several thousand kilometres, the area features a very large number of islands and boasts some of the richest marine, flora and fauna biodiversity on Earth.
The main demographic difference that sets Maritime Southeast Asia apart from modern Mainland Southeast Asia is that its population predominantly belongs to Austronesian groups. The region contains some of the world's most highly urbanized areas: Greater Jakarta, Greater Kuala Lumpur, Metro Manila, and Singapore; and yet a majority of islands in this vast region remain uninhabited by humans.
