Palladium(II) iodide is an inorganic compound of palladium and iodine. It is commercially available, though less common than palladium(II) chloride, the usual entry point to palladium chemistry.

Historically, the quantity of palladium in a sample may be determined gravimetrically by precipitation as palladium(II) iodide. Unlike the chloride and bromide, palladium(II) iodide is not quite as soluble in excess iodide.[1]
