The asymmetric unit of the title compound, C23H16O2, contains two independent mol­ecules in which the dihedral angles between the anthracene ring system and the benzene ring are 73.0 (3) and 73.3 (3)°. In both independent mol­ecules, the hy­droxy group is involved in an intra­molecular O—H⋯O hydrogen bond. The crystal packing is stabilized by π–π inter­actions [centroid–centroid distances = 3.6518 (9), 3.7070 (9) and 3.7632 (9) Å] and weak inter­molecular C—H⋯O hydrogen bonds.
