Diphenic acid is an organic compound with the formula (C₆H₄CO₂H)₂. It is the most studied of several isomeric dicarboxylic acids of biphenyl. It is a white solid that can be prepared in the laboratory from anthranilic acid via the diazonium salt.^[1] It is the product of the microbial action on phenanthrene.^[2]

The compound forms a variety of coordination polymers.^[3] It also exhibits atropisomerism.
