Trochocyathus

Trochocyathus is a genus of corals in the family Caryophylliidae. Living species are found in waters near Hawai'i at depths of 64 to 1020 m. Fossil species are found as far back as the latest Paleocene in the Dilwyn Formation of Australia, in the late Cretaceous in the Woodbury Formation of New Jersey, and in Suffolk.

Platycyathus is sometimes regarded as a subgenus within Trochocyathus.
