The 2012 Atlantic hurricane season was the final year in a string of three consecutive very active seasons since 2010, with 19 tropical storms. The 2012 season was also a costly one in terms of property damage, mostly due to Hurricane Sandy. The season officially began on June 1 and ended on November 30, dates that conventionally delimit the period during each year in which most tropical cyclones form in the Atlantic Ocean. However, Alberto, the first named system of the year, developed on May 19 – the earliest date of formation since Subtropical Storm Andrea in 2007. A second tropical cyclone, Beryl, developed later that month. This was the first occurrence of two pre-season named storms in the Atlantic basin since 1951. It moved ashore in North Florida on May 29 with winds of 65 mph (105 km/h), making it the strongest pre-season storm to make landfall in the Atlantic basin. This season marked the first time since 2009 where no tropical cyclones formed in July. Another record was set by Hurricane Nadine later in the season; the system became the fourth-longest-lived tropical cyclone ever recorded in the Atlantic, with a total duration of 22.25 days. The final storm to form, Tony, dissipated on October 25 – however, Hurricane Sandy, which formed before Tony, became extratropical on October 29.

Pre-season forecasts by the Colorado State University (CSU) called for a below average season, with 10 named storms, 4 hurricanes, and 2 major hurricanes. The National Oceanic and Atmospheric Administration (NOAA) issued its first outlook on May 24, predicting a total of 9–15 named storms, 4–8 hurricanes, and 1–3 major hurricanes; both agencies noted the possibility of an El Niño, which limits tropical cyclone activity. Following two pre-season storms, the CSU updated their forecast to 13 named storms, 5 hurricanes, and 2 major hurricanes, while the NOAA upped their forecast numbers to 12–17 named storms, 5–8 hurricanes, and 2–3 major hurricanes on August 9. Despite this, activity far surpassed the predictions.

Impact during the 2012 season was widespread and significant. In mid-May, Beryl moved ashore the coastline of Florida, causing 3 deaths. In late June and early August, Tropical Storm Debby and Hurricane Ernesto caused 10 and 13 deaths after striking Florida and the Yucatán, respectively. In mid-August, the remnants of Tropical Storm Helene killed two people after making landfall in Mexico. At least 41 deaths and $2.39 billion^{[nb 1]} were attributed to Hurricane Isaac, which struck Louisiana on two separate occasions in late August. However, by far the costliest, deadliest and most notable cyclone of the season was Hurricane Sandy, which formed on October 22. After striking Cuba at Category 3 intensity on the Saffir–Simpson hurricane wind scale, the hurricane moved ashore the southern coastline of New Jersey. Sandy left 286 dead and $68.7 billion worth of damage in its wake, making it the fifth-costliest Atlantic hurricane on record, behind only Hurricane Maria in 2017, Hurricane Katrina in 2005, Hurricane Ian in 2022, and Hurricane Harvey in 2017. Collectively, the season's storms caused at least 355 fatalities and about $71.6 billion in damage, making 2012 the deadliest season since 2008 and the costliest since 2005.
