The List of Atlantic hurricanes in the 18th century encompasses all known Atlantic tropical cyclones from 1700 to 1799. While not all data for every storm that occurred is available, some parts of the coastline were populated enough to give data of hurricane occurrences.
The 1780 Atlantic hurricane season was extraordinarily destructive, and was the deadliest Atlantic hurricane season in recorded history with over 25,000 deaths. Four different hurricanes, three in October and one in June, caused at least 1,000 deaths each; this event has never been repeated and only in the 1893 and 2005 seasons were there two such hurricanes. The season also held the deadliest Atlantic tropical cyclone of all time.
