Maritime Southeast Asia is the maritime region of Southeast Asia as opposed to mainland Southeast Asia and comprises Brunei, East Malaysia, East Timor, Indonesia, Singapore, and the Philippines.
Maritime Southeast Asia is sometimes also referred to as "island Southeast Asia" or "insular Southeast Asia".
This region differs from Indochina in that its populations predominantly belong to the Austronesian (Malayo-Polynesian) group, and exhibit various maritime-based, tribal, and largely non-sinicized cultures.
Over 350 million people live in the region, with the most populated island being Java. The people living there are predominantly from Austronesian subgroupings and correspondingly speak western Malayo-Polynesian languages. This region of Southeast Asia shares social and cultural ties with the peoples of mainland Southeast Asia and with other Austronesian peoples in the Pacific. The main religions in this region are Islam, Christianity, Buddhism, Hinduism, and traditional Animism.
