Wallisian or ʻUvean (Wallisian: Fakaʻuvea) is the Polynesian language spoken on Wallis Island (also known as ʻUvea). The language is also known as East Uvean to distinguish it from the related West Uvean spoken on the outlier island of Ouvéa (near New Caledonia). Wallisian tradition holds that the latter island was colonised from Wallis Island in ancient times.
Classified by linguists as a Nuclear Polynesian language, Wallisian is closely related to other Polynesian languages including Tongan and Samoan.
