The wardroom is the mess cabin or compartment for commissioned naval officers above the rank of midshipman on a warship or other military vessel. Although the term typically relates to officers in a navy, it is also applicable to marine officers and coast-guard officers in those countries that have such service branches. On larger vessels, such as aircraft carriers of the United States Navy, there may be more than one wardroom. The designation "wardroom" may also be used on stone frigates to refer to similar officer-mess facilities at naval, marine, and coast-guard installations ashore.
