Chedighaii is an extinct genus of marine bothremydid side-necked turtle that inhabited eastern and south-central North America during the Campanian stage of the Late Cretaceous.

The genus name is derived from ch’ééh digháhii, the Navajo word for turtle.

[1] The type species, C. hutchisoni was named in 2006 by Gaffney et al. for a specimen, KUVP 14765, consisting only of a skull.

The specimen was found in the San Juan Basin of New Mexico, USA in the Hunter Wash Member of the Kirtland Formation.

[3] The other species, C. barberi, was initially classified in Podocnemis and then Bothremys, and had a more easterly distribution along the coastal margins of Appalachia.
