The 1974 Atlantic hurricane season was a destructive and deadly hurricane season. In terms of overall activity, it was near average, with eleven named storms forming, of which four became hurricanes. Two of the four became major hurricanes, which are Category 3 or higher systems on the Saffir–Simpson scale. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic Ocean.
The first system, a tropical depression, developed over the Bay of Campeche on June 22 and dissipated by June 26. The most intense storm of the season was Hurricane Carmen, which struck the Yucatán Peninsula at Category 4 intensity and Louisiana at Category 3 intensity.
