In the title compound, [CoBr2(C12H12N2)], the CoII atom is four-coordinated in a distorted tetrahedral geometry by two N atoms from a 6,6'-dimethyl-2,2'-bipyridine ligand and by two terminal Br atoms. Intermolecular C-H...Br hydrogen bonds and [pi]-[pi] stacking between the pyridine rings in the bc plane [centroid-centroid distance = 3.725 (3) Å] are present in the crystal structure.
