In the title compound, C(8)H(5)F(3)O(2), 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 carb-oxy-lic 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.
