The PtII ion in the title complex, [PtBr2(C10H9N3)], is four-coordinated in an essentially square-planar environment by two N atoms from a chelating di-2-pyridyl­amine (dpa) ligand and two Br− anions. The dpa ligand is not planar, with the dihedral angle between the pyridine rings being 40.8 (2)°. The complex mol­ecules are stacked in columns along [001] through π–π inter­actions between the pyridine rings [centroid–centroid distances = 3.437 (3) and 3.520 (3) Å]. Inter­molecular N—H⋯Br hydrogen bonds connect the mol­ecules into chains running along [010]. Intra­molecular C—H⋯Br interactions are also observed.
