In the title compound, C14H9F3N2, the mean planes of the benzimidazole ring system and the tri-fluoro-methyl-substituted benzene ring form a dihedral angle of 30.1 (1)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into chains along [010]. Weak C-H⋯F hydrogen bonds and a weak C-H⋯π inter-action connect the chains into a two-dimensional network parallel to (001).
