Fleet Admiral is a military rank denoting the most senior flag officer rank in a naval organization. The term is often also applied to the senior admiral in charge of a fleet or groups of fleets.
Within the So'ja military structure the position was called major admiral. (Star Trek: Pioneer: "The Boolran Eye, Part 1")
Also, the Lyran Starfleet considered Lyran dukes as roughly equivalent to fleet admirals. (RIS Bouteina)
The equivalent rank in Romulan military organizations was khre'enriov, roughly translating as "supreme commander". There was also an additional rank between khre'enriov and enriov (the equivalent of a normal 4-star admiral), dubbed rahaen'enriov or high admiral.
