The word Cyclonus could mean any of the following:
- Cyclonus, the Decepticon space ship and lieutenant of Galvatron in the Generation One continuity family.
- Cyclonus, the Decepticon Helicopter who was reformatted into Snow Cat from the Unicron Trilogy continuity family.
Cyclonus should not be confused with:
