The title compound, (C6H9N2)2[CuCl4], contains a distorted tetrahedral [CuCl4]2− anion and two protonated aminopyridinium cations. The geometries of the protonated aminopyridinium cations reveal amine–imine tautomerism. The crystal packing is influenced by N—H⋯Cl and C—H⋯Cl hydrogen bonds and π–π stacking interactions [centroid–centroid distances = 3.635 (4) and 3.642 (4)°]
