In the title compound, C13H9FO3, the dihedral angle between the two benzene rings is 70.99 (5)°. In the crystal structure, mol­ecules are linked into dimers by centrosymmetric O—H⋯O inter­actions, generating R22(8) ring motifs. These dimers are linked into a two-dimensional array, parallel to the ab plane, by two different C—H⋯O inter­actions. A weak C—H⋯π inter­actions is also present.
