Dysprosium(II) chloride (DyCl₂), also known as dysprosium dichloride, is an ionic chemical compound of dysprosium and chlorine. This salt is a reduced compound, as the normal oxidation state of dysprosium in dysprosium compounds is +3.

Dysprosium dichloride is glossy black in appearance. The salt is damaged by oxidation on exposure to air. It is an electrical insulator.

The structure is the same as for strontium bromide, ytterbium dichloride, and terbium dichloride. There are two forms. The low temperature form is below 652 °C. It is orthorhombic with unit cell dimensions a=6.69, b=6.76, and c=7.06 Å.
