The title compound, C(9)H(7)IN(+)·Cl(-)·2H(2)O, was obtained during the synthesis of 8-iodo-quinoline from 8-amino-quinoline using the Sandmeyer reaction. The 8-iodo-quinolinium ion is almost planar. Solvent water mol-ecules and chloride ions form a hydrogen-bonded chain along the c axis via O-H⋯Cl links. The 8-iodo-quinolinium ions, which are packed along the c axis with cationic aromatic π-π stacking (centroid-centroid distance = 3.624 Å), are linked to the chain via N-H⋯O hydrogen bonds.
