Zirconyl chloride is the inorganic compound with the formula of [Zr₄(OH)₈(H₂O)₁₆]Cl₈(H₂O)₁₂, more commonly written ZrOCl₂·8H₂O, and referred to as zirconyl chloride octahydrate. It is a white solid and is the most common water-soluble derivative of zirconium. A compound with the formula ZrOCl₂ has not been characterized.^[1]

The salt is produced by hydrolysis of zirconium tetrachloride or treating zirconium oxide with hydrochloric acid.^[2] It adopts a tetrameric structure, consisting of the cation [Zr₄(OH)₈]⁸⁺. features four pairs of hydroxide bridging ligands linking four Zr⁴⁺ centers. The chloride anions are not ligands, consistent with the high oxophilicity of Zr(IV).^[1] The salt crystallizes as tetragonal crystals.^[3]
