In the title complex, [CuCl2(C10H7N3S)(C2H5OH)], the CuII ion is five-coordinated in a distorted square-pyramidal geometry by two N atoms from a 2-(1,3-thia­zol-4-yl)-1H-benzimidazole ligand, one O atom from an ethanol mol­ecule and two Cl atoms. In the crystal, O—H⋯Cl and N—H⋯Cl hydrogen bonds link the complex mol­ecules into a layer parallel to (100). π–π inter­actions between the thia­zole rings are observed [centroid–centroid distance = 3.749 (3) Å].
