Diphenylmethane is an organic compound with the formula (C₆H₅)₂CH₂. The compound consists of methane wherein two hydrogen atoms are replaced by two phenyl groups. Diphenylmethane forms a common skeleton in organic chemistry; the diphenylmethyl group is also known as benzhydryl.

It is prepared by the Friedel-Crafts alkylation of benzyl chloride with benzene in the presence of a Lewis acid such as aluminium trichloride:^[1]

C₆H₅CH₂Cl + C₆H₆ → (C₆H₅)₂CH₂ + HCl
