Hurricane Maria was a deadly Category 5 hurricane that devastated the northeastern Caribbean in September 2017, particularly in the U.S. territory of Puerto Rico, which accounted for 2,975 of the 3,059 deaths.[1][2] It is the deadliest and costliest hurricane to strike the island of Puerto Rico, and is the deadliest hurricane to strike the country of Dominica and the territory of the U.S. Virgin Islands. The most intense tropical cyclone worldwide in 2017, Maria was the thirteenth named storm, eighth consecutive hurricane, fourth major hurricane, second Category 5 hurricane, and deadliest storm of the extremely active 2017 Atlantic hurricane season. Maria was the deadliest Atlantic hurricane since Mitch in 1998, and the tenth most intense Atlantic hurricane on record. Total monetary losses are estimated at upwards of $91.61 billion (2017 USD), mostly in Puerto Rico, ranking it as the fourth-costliest tropical cyclone on record.

Maria became a tropical storm on September 16 east of the Lesser Antilles and rapidly intensified to Category 5 strength just before making landfall on Dominica on September 18. After crossing the island, Maria achieved its peak intensity with maximum sustained winds of 175 mph (282 km/h) and a pressure of 908 mbar (hPa; 26.81 inHg). On September 20, an eyewall replacement cycle weakened Maria to a high-end Category 4 hurricane by the time it struck Puerto Rico. Passing north of The Bahamas, Maria gradually degraded and weakened, swinging eastward over the open Atlantic and dissipating by October 2.

Maria brought catastrophic devastation to the entirety of Dominica, destroying housing stock and infrastructure beyond repair, and practically eradicating the island's lush vegetation. The neighboring islands of Guadeloupe and Martinique endured widespread flooding, damaged roofs, and uprooted trees. Puerto Rico suffered catastrophic damage and a major humanitarian crisis; most of the island's population suffered from flooding and a lack of resources, compounded by a slow relief process. The storm caused the worst electrical blackout in US history, which persisted for several months.[3] Maria also landed in the northeast Caribbean during relief efforts from another Category 5 hurricane, Irma, which crossed the region two weeks prior.

The total death toll is 3,059: an estimated 2,975 in Puerto Rico,[4][5] 65 in Dominica, 5 in the Dominican Republic, 4 in Guadeloupe, 4 in the contiguous United States, 3 in the United States Virgin Islands, and 3 in Haiti. Maria was the deadliest hurricane in Dominica since the 1834 Padre Ruíz hurricane[6] and the deadliest in Puerto Rico since the 1899 San Ciriaco hurricane.[7] This makes it the deadliest named Atlantic hurricane of the 21st century to date.
