List of disasters in the United States by death toll

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.

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. It does not include death tolls from the American Civil War. Due to inflation, the monetary damage estimates are not comparable. Unless otherwise noted, the year given is the year in which the currency's valuation was calculated. This list is not comprehensive in general and epidemics are not included.
