Pentecost Island is one of the 83 islands that make up the South Pacific nation of Vanuatu.

It lies 190 kilometres (120 mi) due north of capital Port Vila. Pentecost Island is known as Pentecôte in French and Pentikos in Bislama. The island was known in its native languages by names such as Vanu Aroaroa, although these names are not in common use today. Pentecost has also been referred to as Raga or Araga, a tribal name that originated in the north but is now widely applied to the whole island. In old sources it is occasionally referred to as Whitsuntide Island.
