Tanema (Tetawo, Tetau) is a nearly extinct language of the island of Vanikoro, in the easternmost province of the Solomon Islands.

As of 2012, Tanema is only spoken by one speaker, Lainol Nalo.

[1][3] Like its neighbour Lovono, it has been replaced by Teanu, the main language of Vanikoro.

The late Emele Mamuli was a prolific storyteller who could speak fluently the three languages of Vanikoro: Teanu, Lovono and Tanema.

Some information on the languages of Vanikoro, including Tanema, can be found in François (2009) for the grammar, and François (2021) for the lexicon.
