Vanadium iodide is the inorganic compound with the formula VI3. It is generated by reacting vanadium powder with iodine and is black and hygroscopic. It dissolves in water to give green solutions that are characteristic of V(III) ions. The atomic weight of vanadium iodide is 79.4.

In organic synthesis it acts as an intermediate for the preparation of other vanadium(III) compounds and is used as a catalyst in the production of ethylene propylene diene monomer rubber and polyethylene. It is also used in the manufacture of organic light-emitting diodes. It is a precursor to other vanadium(III) complexes such as the organovanadium compounds. It also serves as an oxidizing agent and an etching agent for metals such as aluminum.

It is an electrophile and can be reduced with a platinum electrode in acetone to form the tris chelates of vanadium(III) with acetylacetonate, [V(SacSac)3]; thioacetylacetonate, [V(SacTac)3]; and monothioacetylacetonate,[V(SacAc)3]. The magnetic properties of these complexes show that there is increasing delocalisation of the unpaired electrons from the metal atom to the ligand as the sulphur content of the ligand increases.
