Big Nambas (native name V'ənen Taut) is an Oceanic language spoken by about 3,400 people (as of 2001[update]) in northwest Malekula, Vanuatu.

Approximately nineteen villages in the Big Nambas region of the Malekula Interior use the language exclusively with no variation in dialect.

A Big Nambas translation of the Bible has been completed recently by Andrew Fox.

The consonants /t β r l n/ all exhibit phonemic gemination when two identical ones occur between syllables.

Linguolabial consonants are often marked with an apostrophe in the orthography to distinguish them from their bilabial counterparts.
