This is a list of sovereign states without armed forces. Dependent territories (such as Bermuda, Guam, and the Northern Mariana Islands) whose defence is the responsibility of another country or an army alternative are excluded. The term armed forces refers to any government-sponsored defense used to further the domestic and foreign policies of their respective government. Some of the countries listed, such as Iceland and Monaco, have no standing armies but still have a non-police military force.

Many of the 21 countries listed here typically have had a long-standing agreement with a former colonial or protecting power; one example of the latter is the agreement between Monaco and France, which has existed for at least 300 years. Similarly, the Compact of Free Association countries of the Federated States of Micronesia (FSM), the Marshall Islands, and Palau rely on the United States for their defence. They ensure their national security concerns are addressed through annual Joint Committee Meetings to discuss defence matters with the U.S. Indo-Pacific Command. Andorra has a small army, and can request defensive aid if necessary, while Iceland has a unique agreement since 1951 with the United States which requires them to provide defence to Iceland when needed, although permanent armed forces have not been stationed there since 2006.

The remaining countries are responsible for their own defence, and operate either without any armed forces, or with limited armed forces. Some of the countries, such as Costa Rica and Grenada, underwent a process of demilitarization. Other countries were formed without armed forces, such as Samoa over 60 years ago; the primary reason being that they were, or still are, under protection from another nation at their point of independence.
