A bosonic model with unfrustrated hopping and short-range repulsive interactions is constructed that realizes a Z3 fractionalized insulator phase in two dimensions and in zero magnetic field. Such a phase is characterized as having gapped charged excitations that carry fractional electrical charge 1/3 and also gapped Z3 vortices above the topologically ordered ground state.
