Zirconium(IV) iodide is the chemical compound with the formula ZrI4. It is the most stable and most readily available iodide of zirconium.

This orange-coloured species is volatile, subliming as intact tetrahedral ZrI4 molecules. It is prepared by the direct reaction of powdered zirconium metal and iodine.[1]
