Holikachuk (own name: Doogh Qinag[5]) is a recently extinct Athabaskan language formerly spoken at the village of Holikachuk (Hiyeghelinhdi) on the Innoko River in central Alaska.

In 1962, residents of Holikachuk relocated to Grayling on the lower Yukon River.

Holikachuk is intermediate between the Deg Xinag and Koyukon languages, linguistically closer to Koyukon but socially much closer to Deg Xinag, which has influenced it.

Though it was recognized by scholars as a distinct language as early as the 1840s, it was only definitively identified in the 1970s.

[7] In March 2012, the last living fluent speaker of Holikachuk died in Alaska.
