A list of wars or military conflicts involving the United States, beginning with the American Revolution of 1774. Significant wars are included on the list, along with the major campaigns conducted within those wars. Individual military actions conducted outside of a war are also featured. Skirmishes and military actions related to the Cold War or the conflicts between Native Americans and the United States military, for example, are included on this list of American wars.

When possible, the combatants engaging the United States are also listed, though this becomes more challenging when dealing with the "War on Terror"-related conflicts of the early 21st Century and its collection of insurgents and enemy combatants.
