In the title compound, C(15)H(13)BrN(2), the benzimidazole group is almost planar, as indicated by the dihedral angle of 2.6 (3)° between the best planes through the benzene and imidazole rings. The best plane through the attached benzene makes an angle of 44.5 (2)° with the best plane through the benzimidazole system. C-H⋯π inter-actions are observed in the crystal structure.
