Titanium(II) iodide is the inorganic compound with the formula TiI₂. It is a black micaceous solid. It adopts the cadmium iodide structure, featuring octahedral Ti(II) centers. It arises via the reaction of the elements:^[1]

Ti + I₂ → TiI₂

As such, it is an implied intermediate in the van Arkel–de Boer process for the purification of titanium metal.
