A rostrum (Latin for "beak") is an anatomical structure resembling a bird's beak, such as the snout of a crocodile or dolphin or the foremost extension of a crustacean's carapace. Since the rostrum is typically located about the thorax of an arthropod, it is differentiated from the cauda or tail.

The anterior end of the corpus callosum in the Human brain is continuous with a region called rostrum.
