List of disasters in the United States by death toll

Steamboat boiler explosions were a common cause of 19th-century mass-casualty events in the United States.

This list of United States disasters by death toll includes disasters that occurred either in the United States, at diplomatic missions of the United States, or incidents outside of the United States in which a number of U.S. citizens were killed.

• Domestic deaths due to war in America are included except the American Civil War. For stats on this and U.S. military deaths in foreign locations, see United States military casualties of war and list of battles with most United States military fatalities.
