Alyutor (also called Alutor, Aliutor or Olyutor) is a severely endangered language of Russia that belongs to the Chukotkan branch of the Chukotko-Kamchatkan languages, by the Alyutors. It is spoken by 172 speakers in the 2021 Russian census.

The Alutor are the indigenous inhabitants of the northern part of the Kamchatka Peninsula. The language is unwritten and moribund; in the 1970s residents of the chief Alutor village of Vyvenka under the age of 25 did not know the language. In recent years, the Vyvenka village school has started teaching the language. Until 1958, the language was considered the "village" (settled) dialect of the Koryak language, but it is not intelligible with traditionally nomadic varieties of Koryak. The autonym [ˈnəməlʔən] (also Нәмәлъу) means "villager" or "settled person".

Alyutor has six vowels, five of which may be long or short. The schwa /ə/ cannot be long.

There are 18 consonants in Alyutor.

Stress generally falls on the second syllable of polysyllabic words, and on the first syllable of disyllabic words, e.g.:

An open syllable containing schwa cannot be stressed. As a consequence, if a disyllabic term begins with such a syllable, the stress is shifted to the last syllable and thereafter a new, epenthetic syllable is added at the end, e.g.:

The final syllable of a word is never stressed.

All Alyutor syllables begin with a single consonant. If the vowel is short, including a schwa, they may also close with a single consonant. Consonant clusters are not permitted in the word initial or word final positions. The schwa is used to break up disallowed clusters.
