Neocathartes is an extinct genus of gruiform bird. It contains a single named species, Neocathartes grallator ("walking new turkey vulture"), known from some fossil bones found in Late Eocene (c.37-34 mya) Washakie Formation deposits of Wyoming. Similar bones have been recovered from the Early Eocene Willwood Formation. The genus originally set up by Wetmore, Eocathartes, was already in use for an unrelated fossil bird from Germany, so a new genus had to be established for the Wyoming fossil (Wetmore, 1950).
