Gornogomphodon is an extinct genus of cynodonts from the Gorno Formation of Bergamo, Italy.

It existed during the Middle Carnian age of the Late Triassic (around 216.5 to 228.0 million years ago).

[1] Gornogomphodon is known only from a fossil jaw fragment with three transversely elongate teeth preserved.

It was proposed to be the remains of a pycnodont fish but further studies eventually made this hypothesis unlikely.

The overall morphology of the teeth suggests they are the upper postcanines of the right maxilla of a gomphodont (herbivorous cynodonts), but they also possess unique characteristics that make their taxonomic assignment difficult.
