Niuafoʻouan is the language spoken on Tonga's northernmost island, Niuafoʻou.

Niuafoʻouan has traditionally been classified as closest to ʻUvean and Tokelauan, in an East Uvean–Niuafo'ou branch. However, recent research suggests that it is closest to its neighbor, Tongan, as one of the Tongic languages.
