The 1991 Atlantic hurricane season officially began June 1, 1991, and ended on November 30, 1991. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin.
The season was inactive, with only eight named storms forming. In spite of the inactivity, the season had one of the most noteworthy Atlantic hurricanes in history, Hurricane Bob, which briefly reached Category 3 intensity before weakening to a Category 2 and making landfall in Rhode Island. Bob delivered significant impacts to New England, causing $1.5 billion (1991 USD) in damage. Bob killed at least 20 people, and will be long remembered. Other notable storms include Hurricane Grace, whose remnants contributed to the formation of the 1991 Halloween Nor'easter, which in itself ultimately helped to fuel Hurricane Eight, the final storm of the 1991 season.

List of Storm Names
Accumulated Cyclone Energy (ACE) Rating
The list below shows the ACE for each storm in the season. The ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed for, so hurricanes that lasted a long time, as well as particularly strong hurricanes, have higher ACEs.
- Ana - 1.25250
- Bob - 7.96500
- Claudette - 14.01250
- Danny - 2.06250
- Erika - 1.97000
- Fabian - 0.76250
- Grace - 3.82500
- Eight - 2.11750
The World Meteorological Organization retired one named from the 1991 season during their Spring meeting in 1992: Bob. It was replaced with Bill for the 1997 season, and was not retired then, nor after its use in 2003.
