In the title compound, C16H14NS+·I-, the cation has an E configuration about the C=C double bond of the ethylene unit. The dihedral angle between the thiophene ring and the quinolinium ring system is 11.67 (11)°. A weak C-H...S intramolecular interaction involving the thiophene ring generates an S(5) ring motif. In the crystal structure, the iodide ion, located between the cations arranged in an antiparallel manner, forms weak C-H...I interactions. The crystal structure is further stabilized by a [pi]-[pi] interaction between the thiophene and pyridine rings; the centroid-centroid distance is 3.6818 (13) Å.
