Hexahydroxydiphenic acid is an organic compound with the formula [(HO)3C6HCO2H]2. It is the oxidatively coupled derivative of gallic acid[2] It is a white solid, although samples are typically brown owing to oxidation.

Ellagic acid.

Hexahydroxydiphenic acid is a component of some ellagitannins,[3] such as casuarictin. Luteic acid is the monolactone and ellagic acid is the dilactone of hexahydroxydiphenic acid.
