In the title compound, [Co(C8H7BrNO)3], the CoIII ion is coordinated in a slightly distorted octa­hedral environment by three N atoms and three O atoms from three bidentate 4-bromo-2-(methyl­imino­meth­yl)phenolate ligands. The dihedral angles between the benzene rings are 82.6 (2), 57.1 (2) and 62.9 (2)°. In the crystal, mol­ecules are linked by pairs of weak C-H...Br hydrogen bonds, forming inversion dimers.
