In the title compound, [CoCl2(C6H8N2)2], the CoII ion is four-coordinated by two pyridine N atoms from the 2-amino-3-methylpyridine ligands and two chloride ions in a distorted tetrahedral geometry. A weak intramolecular N—H⋯Cl interaction occurs. The crystal packing is stabilized by intermolecular N—H⋯Cl and C—H⋯Cl hydrogen-bond interactions
