Tungsten hexachloride is an inorganic chemical compound of tungsten and chlorine with the chemical formula W Cl₆. This dark violet-blue compound exists as volatile crystals under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. Other examples of charge-neutral hexachlorides are rhenium(VI) chloride and molybdenum(VI) chloride. The highly volatile tungsten hexafluoride is also known.

As a d⁰ atom, tungsten hexachloride is diamagnetic.
