Palaearctonyx ("ancient bear's claw") is an extinct genus of omnivorous placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.

[2][3][4][5] Palaearctonyx was named by Matthew in 1909 and it was assigned to family Miacidae.

Later, it was assigned to Caniformia by Flynn and Galiano in 1982,[6] and then back to Miacidae by Flynn in 1998.

[4] From 2010 and later, this genus was assigned to clade Carnivoraformes.
