Biritai (Biri) is a Lakes Plain language of Papua, Indonesia. It is named after Biri village in East Central Mambermano District, Mamberamo Raya Regency.

The following inventory is taken from Donohue (2017), with a very small consonant inventory typical of the Lakes Plain languages.

In an earlier paper co-authored by Donohue, the approximants /j w/ are also included as phonemes. The authors note that Biritai is typologically unusual for missing series of velar, nasal and liquid consonants.

Biritai is tonal.^{[citation needed]}
