Timeline of the 1972 Atlantic hurricane season

The 1972 Atlantic hurricane season is one of five Atlantic hurricane seasons not to have any major hurricanes, the others being 1968, 1986, 1994, and 2013. Although Subtropical Storm Alpha formed on May 23, the season officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's final storm, Subtropical Storm Delta, dissipated on November 7.

The season produced nineteen tropical or subtropical cyclones, of which seven intensified into tropical or subtropical storms; three became hurricanes, but none further intensified into major hurricanes, the first such occurrence since the 1968 season. Despite the inactivity, the 1972 season resulted in one of the worst natural disasters in American history, Hurricane Agnes. Agnes was a weak but large storm that initially made landfall on the Florida Panhandle before moving up the eastern United States. The hurricane killed 122 people and caused $2.1 billion (1972 USD) in damage, mostly due to flooding in Pennsylvania and New York.

This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
