Metoma is a small volcanic island in Torba Province of Vanuatu in the Pacific Ocean.

The summit elevation is 115 m. Metoma is populated by robber crabs (Birgus latro), the world's largest terrestrial invertebrates.

[citation needed] The village in the south of the island is called Rival.

The island is locally called Mētome [metɔmə] in Lo-Toga.

The official name Metoma [metoma] is spelled according to the Mota language, which missionaries chose as a reference in the area; the latter form is conservative of the ancient form *metoma which can be reconstructed in the ancestral language of the Torres and Banks Islands.
