The title benzimidazole derivative, C24H18FN3O2, is T-shaped, with the 4-cyanobenzene and 4-fluorobenzyl rings inclined to the imidazole ring system by 32.89 (10) and 83.63 (10)°, respectively, and by 89.00 (12)° to one another. The terminal methyl group of the ethylcarboxylate group is disordered over three sites and was refined with a fixed occupancy ratio of 1/3:1/3:1/3. In the crystal, molecules are essentially linked by offset π–π interactions, involving inversion-related imidazole rings [inter-centroid distance = 3.763 (1) Å], and stack along the b-axis direction.
