Iridium(IV) fluoride is a chemical compound of iridium and fluorine, with the chemical formula IrF₄ and is a dark brown solid.{{Greenwood&Earnshaw}} Early reports of IrF₄ prior to 1965 are questionable and appear to describe the compound IrF₅. The solid can be prepared by reduction of IrF₅ with iridium black or reduction with H₂ in aqueous HF.{{cite journal | title = Reductive syntheses of transition metal fluoride compounds.

RhF₄, PdF₄ and PtF₄ have been found to have the same structure. Wells A.F. (1984) Structural Inorganic Chemistry 5th edition Oxford Science Publications {{ISBN|0-19-855370-6}} The structure has 6 coordinate, octahedral, iridium where two edges of the octahedra are shared and the two unshared fluorine atoms are cis to one another.
