The Raja Ampat–South Halmahera languages are a branch of Malayo-Polynesian languages of eastern Indonesia. They are spoken on islands in the Halmahera Sea, and on its margins from the south-eastern coast of Halmahera to the Raja Ampat Islands off the western tip of New Guinea.
The languages of the Raja Ampat Islands show a strong Papuan substratum influence; it is not clear that they are actually Austronesian as opposed to relexified Papuan languages.
Remijsen (2001) and Blust (1978) linked the languages of Raja Ampat to the South Halmahera languages.
