Tungsten(III) chloride is the inorganic compound with the formula W₆Cl₁₈. It is a cluster compound. It is a brown solid, obtainable by chlorination of tungsten(II) chloride.^[2] Featuring twelve doubly bridging chloride ligands, the cluster adopts a structure related to the corresponding chlorides of niobium and tantalum. In contrast, W₆Cl₁₂ features eight triply bridging chlorides.

A related mixed valence W(III)-W(IV) chloride is prepared by reduction of the hexachloride with bismuth:^[3]

9 WCl₆ + 8 Bi → 3 W₃Cl₁₀ + 8 BiCl₃
