The Chukotko-Kamchatkan languages are a language family of Siberia. The Chukotko-Kamchatkan languages are sometimes grouped with other unrelated language families as the Paleosiberian languages.

The family consists of five languages:

• Chukchi, also known as Chukot
• Koryak
• Alutor, which was considered a dialect of Koryak until recently, but is now recognized as a separate language
• Kerek, which was formerly considered a dialect of Chukchi, but is now recognized as a separate language. In 1997 only two elderly speakers remained, so the language may now be extinct, with the rest of the ethnic group now assimilated into the Chukchi.
• Itelmen (also called Kamchadal), which had 100 or fewer speakers in 1991, mostly of the older generation.
