Dysprosium(III) telluride is an inorganic compound, one of the tellurides of dysprosium, with the chemical formula Dy<sub>2</sub>Te<sub>3</sub>, where Dy is in the +3 oxidation state.
Dysprosium(III) telluride can be obtained by reacting tellurium and dysprosium in a stoichiometric ratio:
Dysprosium(III) telluride reacts with copper(II) telluride at high temperature to obtain phases such as DyCuTe<sub>2</sub>, DyCu<sub>5</sub>Te<sub>4</sub>, and Dy<sub>7</sub>Cu<sub>3</sub>Te<sub>12</sub>. It and cadmium telluride can form CdDy<sub>2</sub>Te<sub>4</sub> at high temperatures:
