The following is a list of wars involving Iceland. Although modern Iceland does not maintain a standing army, navy nor air force, it maintains a militarised coast guard which is in charge of defending the country. The country has deployed a small peacekeeping force internationally on a few occasions. It has never participated in a full-scale war or invasion, and the constitution of Iceland has no mechanism to declare war.
None of the Cod Wars meet any of the common thresholds for a conventional war, and they may more accurately be described as militarised interstate disputes between Iceland and the United Kingdom.
