The 1983 Atlantic hurricane season was the least active Atlantic hurricane season in 53 years, during which four tropical cyclones formed. The season officially began on June 1, 1983, and ended on November 30, dates which conventionally limit the period of each year when tropical cyclones tend to form in the Atlantic. The first named storm, Hurricane Alicia, formed on August 15. The last storm of the season, Tropical Storm Dean, dissipated on September 30. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipations during the season. The timeline also includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned upon.

This season produced seven tropical depressions, of which four became named storms; three attained hurricane status, of which one became a major hurricane, a storm that ranks as a Category 3 or higher on the Saffir-Simpson Hurricane Scale. Hurricane Alicia had its name retired due to the fatalities and severe damage caused in Texas. The storm killed 21 people and caused $2.6 billion (1983 USD; $5.6 billion 2008 USD) in damages, making it the costliest storm, at the time, in Texas history. Hurricane Barry was a weak Category 1 hurricane that traveled almost due west across the Gulf of Mexico for most of its track before making landfall in extreme northern Mexico.
