Gold iodide is a hypothetical chemical compound with the formula Au I₃. Although Au₂I₆ is predicted to be stable,^[1] gold(III) iodide remains an example of a nonexistent or unstable compound.^[2] Attempts to isolate pure samples result in the formation of gold(I) iodide and iodine:

AuI₃ → AuI + I₂
