The Naval Crown (Latin: corona navalis) was a gold crown surmounted with small replicas of the prows of ships. It was a Roman military award, given to the first man who boarded an enemy ship during a naval engagement.

In heraldry a naval crown is mounted atop the shields of coats of arms of the naval vessels and other units belonging to some navies. It is made up of a circlet with the sails and sterns of ships alternating on top.
