We report the discovery of two isolated radio pulsars having the largest inferred surface dipole magnetic fields yet seen in the population: 4.1e1013 G and 5.5e1013 G. These pulsars show apparently normal radio emission in a regime of magnetic field strength where some models predict no emission should occur. They have spin parameters and magnetic fields similar to those of some magnetar candidates, but exhibit very different radiative properties. This demonstrates that if the putative magnetars are indeed isolated neutron stars, their unusual attributes cannot be only a consequence of their large inferred magnetic fields.
