Messapicetus is an extinct genus of beaked whale from the Late Miocene.

It currently holds two species, M. longirostris from the Tortonian of Italy[1] and M. gregarius from the Pisco Formation of Peru.

[2] However, a third unnamed species is represented in the St. Marys Formation of Maryland known from fragmentary material.

[3] M. gregarius is sexually dimorphic, males having tusks which are hypothesized to have been used in intraspecific combat for mates as in extant (living) beaked whales.
