Rapa (or Rapan; autonym Reo Rapa or Reo Oparo) is the language of Rapa, in the Austral Islands of French Polynesia. It is an East Central Polynesian language, along with the Marquesic and Tahitic languages.
The language is sufficiently different from the rest of the Austral languages as to be considered a separate language. It is assumed to have developed in relative isolation for nearly 700 years.
It is not to be confused with the Rapa Nui language.
