The 2015 Atlantic hurricane season was an active North Atlantic hurricane season (mainly due to a minor La Niña event), producing 18 total tropical or subtropical cyclones, 16 total storms, 11 hurricanes, and six major hurricanes. It was tied with the 2003 and 2008 seasons as the tenth most active Atlantic hurricane season on record in terms of total storms.

The most intense storm was Hurricane Danny, which peaked as a Category 5 hurricane on the Saffir-Simpson Hurricane Sc
