The name Fiona has been used for seven tropical cyclones worldwide: three in the Atlantic Ocean, three in the Australian region, and one in the South-West Indian Ocean.
In the Atlantic:
- Tropical Storm Fiona (2010), moderate but disorganized tropical storm, moved in the central Atlantic without threatening land
- Tropical Storm Fiona (2016), weak tropical storm that churned across the open ocean
- Hurricane Fiona (2022), Category 4 hurricane that caused significant damage in Puerto Rico and Atlantic Canada
The name Fiona was retired after the 2022 season due to the extensive amount of damage and loss of life it caused along its track. It will be replaced with Farrah for the 2028 season.
In the Australian region:
- Cyclone Fiona (1971), severe tropical cyclone, made landfall in the northern coast of Australia.
- Cyclone Fiona-Gwenda (1974), operationally considered to be two separate storms, but reduced to one in post-season analysis
- Cyclone Fiona (2003), brought significant rainfall to the Western Australia coast
In the South-West Indian:
- Tropical Depression Fiona (1998), weak tropical cyclone that churned off the coast of Madagascar
