West Uvean (also Uvean or Faga Ouvéa; Fagauvea in the vernacular) is a Polynesian outlier language spoken on the island of Ouvéa, in the Loyalty island group of New Caledonia, and in the capital of Nouméa.

West Uvean has been studied by linguists Françoise Ozanne-Rivierre and Claire Moyse-Faurie.

West Uvean has long been in contact with Iaai, the Southern Oceanic language also spoken on the same island.

This contact has resulted in four vowels being added to the phonemic system of West Uvean; and to a complexification of the syllable structure, allowing for final consonants.

[2] West Uvean is the only Polynesian language to use a quinary numeral system.
