The Chukotko-Kamchatkan or Chukchi–Kamchatkan languages are a language family of extreme northeastern Siberia. Its speakers traditionally were indigenous hunter-gatherers and reindeer-herders. Chukotko-Kamchatkan is endangered. The Kamchatkan branch is moribund, represented only by Western Itelmen, with only 80 elderly speakers left (as of the 2010 Russian census). The Chukotkan branch had close to 7,000 speakers left (as of 2010, the majority being speakers of Chukchi), with a reported total ethnic population of 25,000.

While the family is sometimes grouped typologically and geographically as Paleo-Siberian, no external genetic relationship has been widely accepted as proven. The most popular such proposals have been for links with Eskimo–Aleut, either alone or in the context of a wider grouping.

Less commonly encountered names for the family are Chukchian, Chukotian, Chukotan, Kamchukchee and Kamchukotic. Of these, Chukchian and Chukotian are ambiguous, since both terms are sometimes used to refer specifically to the family's northern branch.

In addition, Luorawetlan (also spelled Luoravetlan) has been in wide use since 1775 as a name for the family, although it is properly the self-designation of one of its constituent languages, Chukchi. The derivative Luorawetlanic may be preferable as a name for the family.

The Chukotko-Kamchatkan family consists of two distantly related dialect clusters, Chukotkan and Kamchatkan. Chukotkan is considered anywhere from one to four languages, whereas there is only one surviving Kamchatkan language, Itelmen.
