In the title compound, C8H5F3O2, a halogenated derivative of benzoic acid, the carboxyl group is tilted by 16.8 (3)° with respect to the plane of the aromatic ring. In the crystal, O—H...O hydrogen bonding gives rise to carboxylic acid dimers, which are further connected into double chains along [1,1/4,1] by C—H...O contacts. C—H...F and C—F...π contacts are also observed.
