In admiralty law prizes are equipment, vehicles, vessels, and cargo captured during armed conflict. The most common use of prize in this sense is the capture of an enemy ship and its cargo as a prize of war. In the past, the capturing force would commonly be allotted a share of the worth of the captured prize. Nations often granted letters of marque that would entitle private parties to capture enemy property, usually ships. Once the ship was secured on friendly territory, it would be made the subject of a prize case: an in rem proceeding in which the court determined the status of the condemned property and the manner in which the property was to be disposed of.

A prize of war is a piece of enemy property or land seized by a belligerent party during or after a war or battle. This term was used nearly exclusively in terms of captured ships during the 18th and 19th centuries.
