Palaihnihan (also Palaihnih) is a small language family of northeastern California. It consists of two closely related languages, both now extinct:
The Palaihnihan family is often connected with the hypothetical Hokan stock. Proposed special relationships within Hokan include Palaihnihan with Shastan (known as Shasta-Achomawi) and within a Kahi sub-group (also known as Northern Hokan) with Shastan, Chimariko, and Karuk.

| Reconstruction of | Palaihnihan languages | 
The original reconstruction of proto-Palaihnihan suffered from poor quality data. David Olmsted's dictionary depends almost entirely upon de Angulo, who did not record the phonological distinctions consistently or well, [1] and carelessly includes Pomo vocabulary from a manuscript in which he (de Angulo) set out to demonstrate that Achumawi and Pomo are not related. [2] William Bright has also pointed out problems with Olmsted's methods of reconstruction. [3] The reconstruction is being refined with newer data. [4]
Good, McFarland, & Paster (2003) conclude there were at least three vowels, *a *i *u, and possibly marginal *e, along with vowel length and ablaut.
Consonants were as follows: [4]
