The principal branches of the Nuclear Malayo-Polynesian languages:
  Sunda–Sulawesi (Chamorro off-map)
  Eastern Malayo-Polynesian (excluding Oceanic)
  Oceanic (vast majority off-map)

The Nuclear Malayo-Polynesian languages are a branch of the Austronesian family, proposed by Wouk & Ross (2002), that are thought to have dispersed from a possible homeland in Sulawesi. They are called nuclear because they are the conceptual core of the Malayo-Polynesian family, including both Malay and Polynesian. Nuclear Malayo-Polynesian is found throughout Indonesia (apart from central Borneo, Sabah, and the north of Sulawesi), and into Melanesia and the Pacific.

Nuclear Malayo-Polynesian languages are Malayo-Polynesian languages that have abandoned the Austronesian alignment inherited from Proto-Malayo-Polynesian syntax. Nuclear Malayo-Polynesian includes the traditional geographic groupings of Central–Eastern Malayo-Polynesian and part of Western Malayo-Polynesian, a part Wouk and Ross call the Sunda–Sulawesi languages. Nuclear Malayo-Polynesian excludes the Borneo–Philippine languages. Sunda–Sulawesi is therefore defined negatively, as those languages of the Greater Sunda Islands and Sulawesi not included in Central–Eastern Malayo-Polynesian. Central–Eastern is an areal group, divergent from the rest of Malayo-Polynesian due to non-Austronesian (Papuan) substrata rather than due to any genealogical relationship.

There are a number of small clusters of languages whose interrelationship remains uncertain. Grouped by geography, they are:
