In the crystal structure of the title compound, C13H8O4, the inversely oriented mol­ecules form inversion dimers through pairs of O—H⋯O hydrogen-bonding inter­actions. An intramolecular O—H⋯O hydrogen bond occurs. In the packing of the mol­ecules, the nearly planar 2-(furan-2-yl)-4H-chromene units [dihedral angle between the chromene and furan rings = 3.8 (1)°] are either parallel or inclined at an angle of 80.7 (1)°
