In the title compound, C(9)H(9)FO(3), the dihedral angle between the carboxyl group and the benzene ring is 79.4 (3)°. In the crystal, mol-ecules form centrosymmetric dimers through pairs of classical O-H⋯O hydrogen bonds. These are further linked by weaker C-H⋯O inter-actions, forming a three-dimensional network.
