Diphenyldichloromethane is an organic compound with the formula (C₆H₅)₂CCl₂. It is a colorless solid that is used as a precursor to other organic compounds.

It is prepared from carbon tetrachloride and anhydrous Aluminium chloride as catalyst in a double Friedel-Crafts alkylation of benzene. Alternatively, benzophenone is treated with phosphorus pentachloride:

It undergoes hydrolysis to benzophenone.

It is used in the synthesis of tetraphenylethylene, diphenylmethane imine hydrochloride and benzoic anhydride.
