In the title compound, [CdBr(2)(C(12)H(12)N(2))], the Cd(II) atom is four-coordinated in a distorted tetra-hedral geometry by two N atoms from a 6,6'-dimethyl-2,2'-bipyridine ligand and two terminal Br atoms. In the crystal, C-H⋯Br hydrogen bonds and π-π stacking inter-actions between the pyridine rings [centroid-centroid distance = 3.763 (5) Å] are present.
