The asymmetric unit of the title compound, (C7H7N2S)2[ZnCl4], contains a network of 2-aminobenzothiazolium cations and tetrahedral [ZnCl4]2− anions. The crystal packing is influenced by cation-to-anion N—H⋯Cl and C—H⋯Cl hydrogen bonds. The [ZnCl4]2− anions have a distorded tetrahedral geometry. Intermolecular π–π stacking interactions are present between neighboring benzene rings, thiazole and benzene rings and neighboring thiazole rings [centroid–centroid distances = 3.711 (2), 3.554 (1), 3.536 (2) and 3.572 (1) Å].
