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

A rostrum is the platform a speaker stands on while giving a speech.

A Rostrum club consists of members who meet to improve their skills in public speaking and meeting procedure. Each club is part of a larger non-profit organisation that promotes and facilitates the improvement of public speaking skills.
