A model is proposed for the Vela pulsar in which the radio emission originates near the surface of the neutron star while the pulsed $gamma$-ray emission is produced by synchrotron radiation near the speed-of-light cylinder. This model can explain the energy flux, double pulse structure, and phase shift (with respect to the radio) of the $gamma$-ray emission, and offers approximate quantitative predictions for other X- and $gamma$-ray fluxes.
