Vice admiral is a senior naval flag officer rank, equivalent to lieutenant general and air marshal. A vice admiral is typically senior to a rear admiral and junior to an admiral. In many navies, vice admiral is a three-star rank with a NATO code of OF-8, although in some navies like the French Navy it is an OF-7 rank, the OF-8 code corresponding to the four-star rank of squadron vice-admiral.

The rank insignia for a vice admiral often involves three stars, but this is not always the case. In the navy of Iraq, vice admiral insignia involves one star. In the navies of Azerbaijan, Bangladesh, China, Cuba, Iran, Mexico, North Korea, and Russia, vice admiral insignia involves two stars, and in the navy of Turkey, vice admiral insignia involves four stars.
