Diphenyl disulfide is the chemical compound with the formula (C₆H₅S)₂. This colorless crystalline material is often abbreviated Ph₂S₂. It is one of the more commonly encountered organic disulfides in organic synthesis. Minor contamination by thiophenol is responsible for the disagreeable odour associated with this compound.
