This is a list of fatal, unprovoked shark attacks that occurred in United States territorial waters by decade in reverse chronological order. Fatal shark attacks that resulted from provocation (such as shooting the shark with a speargun) are not included; neither are attacks that occurred outside U.S. territorial waters (for example, the shark attacks that occurred after the sinking of the USS Indianapolis in World War II would not be included here). Non-fatal shark attacks are not included in this list.
