Dysprosium(III) chloride (DyCl₃), also known as dysprosium trichloride, is a compound of dysprosium and chlorine. It is a white to yellow solid which rapidly absorbs water on exposure to moist air to form a hexahydrate, DyCl₃·6H₂O. Simple rapid heating of the hydrate causes partial hydrolysis to an oxychloride, DyOCl.
