In the molecule of the title compound, C20H16Cl2N2O2, the planar benzimidazole ring system is oriented with respect to the furan and dichlorobenzene rings at dihedral angles of 53.39 (6) and 31.04 (5)degrees, respectively. In the crystal structure, intermolecular C-H center dot center dot center dot Cl hydrogen bonds link the molecules into centrosymmetric R-2(2)(8) dimers. These dimers are connected via a C-H center dot center dot center dot pi contact between the benzimidazole and the furan rings, and pi-pi contacts between the benzimidazole and dichlorobenzene ring systems [centroid centroid distances = 3.505 (1), 3.567 (1), 3.505 (1) and 3.567 (1) angstrom].
