Tropaeum is an extinct genus of ammonites 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 to the genus Lytoceras. The largest species, T. imperator of Australia , had a shell a little over one meter in diameter.
The name "Tropaeum" was applied by paleontologist James De Carle Sowerby, in 1837.
