Tropaeum ("Trophy") is an extinct genus of ammonite cephalopod found throughout the oceans of the world during the Early Cretaceous. As with many other members of the family Ancyloceratidae, there was a trend among species within this genus to uncoil somewhat, in a very similar manner in the genus Lytoceras. The largest species, T. imperator of Australia, had a shell a little over one meter in diameter.
