The Great Hurricane of 1780, also known as Huracán San Calixto, the Great Hurricane of the Antilles, and the 1780 Disaster, is the deadliest Atlantic hurricane on record. Between 20,000 and 22,000 people died when the storm passed through the Lesser Antilles in the Caribbean October 10–16. Specifics on the hurricane's track and strength are unknown since the official Atlantic hurricane database only goes back to 1851.
