We use a self-consistent Hartree-Fock approximation with realistic Coulomb interactions for π-band electrons to explore the possibility of broken symmetry states in weakly disordered ABC-stacked trilayer graphene. The competition between gapped and gapless broken symmetry states and normal states is studied by comparing total energies. We find that gapped states are favored and that, unlike the bilayer case, gapless nematic broken symmetry states are not metastable. Among the gapped states, the layer antiferromagnetic state is favored over anomalous and spin Hall states.
