'''''Neognathodus''''' is an extinct genus of conodonts.

==Use in stratigraphy== The Bashkirian, the oldest age of the Pennsylvanian (also known as Upper Carboniferous), contains six biozones based on conodont index fossils, two of which contain ''Neognathodus'' species: * the zone of ''Neognathodus atokaensis'' * the zone of ''Neognathodus askynensis''

The base of the Moscovian, the second stage in the Pennsylvanian, can biostratigraphically be divided into five conodont biozones, three of which contain ''Neognathodus'' species: * the zone of ''Neognathodus roundyi'' and ''Streptognathodus cancellosus'' * the zone of ''Neognathodus medexultimus'' and ''Streptognathodus concinnus'' * the zone of ''Neognathodus uralicus''
