The fluoronium ion is an inorganic cation with the chemical formula . It is one of the cations found in fluoroantimonic acid.[1] The structure of the salt with the anion, has been determined.[2][3] The fluoronium ion is isoelectronic with the water molecule and the azanide ion.

The term can also refer to organyl substituted species of type H--R, R--R, or R2C=F+. In contrast to the heavier halogens, which have long been known to form open-chain halonium ions (such as ) as well as cyclic haliranium ions, fluorine was not believed to form fluoronium ions of type R--R until the recent characterization of a fluoronium ion locked in a designed cage structure by Lectka and coworkers.[4]
