2021 Atlantic hurricane season (Cooper)

The 2021 Atlantic hurricane season was an extremely active and disastrous season, featuring 19 named storms, 10 hurricanes, and 4 major hurricanes. It was the deadliest season since 2005, as well as the costliest since 2018. Nearly all of the season's destruction was due to three of its major hurricanes — Henri, Mindy, and Nicholas.

The strongest and costliest storm of the season was Hurricane Mindy, which was the first Category 5 Atlantic hurricane since Maria in 2017. The season's deadliest storm was Hurricane Henri. With at least 2,438 fatalities attributed to it and many more missing, Henri was the deadliest Atlantic hurricane since Jeanne of 2004.

Storm names
The following list of names was used for named storms that formed in the North Atlantic in 2021. The names not retired from this list will be used again in the 2027 season. This was the same list used in the 2015 season, with the exception of Elsa and Julian, which replaced Erika and Joaquin, respectively. The names Elsa, Julian, Rose, Sam, and Teresa were used for the first time this year. Two names, Victor and Wanda, were not used during the course of the year.

Retirement
On March 29, 2022, at the 44th session of the RA IV hurricane committee, the World Meteorological Association retired the names Henri, Mindy, and Nicholas from its rotating name lists due to the amount of damage and deaths they caused, and they will not be used again for another Atlantic hurricane. They were replaced with Horatio, Mackenzie, and Nolan for the 2027 season, respectively.
