Diphenylditelluride is the chemical compound with the formula (C₆H₅Te)₂, abbreviated Ph₂Te₂ This orange-coloured solid is the oxidized derivative of the unstable benzenetellurol, PhTeH. Ph₂Te₂ is used as a source of the PhTe unit in organic synthesis.

Ph₂Te₂ is prepared by the oxidation of tellurophenolate, which is generated via the Grignard reagent:

The molecule has C₂ symmetry.
