The collapse of a massive star's core, followed by a neutrino-driven,asymmetric supernova explosion, can naturally lead to pulsar recoils andneutron star kicks. Here, we present a two-dimensional, radiation-hydrodynamicsimulation in which core collapse leads to significant acceleration of afully-formed, nascent neutron star (NS) via an induced, neutrino-drivenexplosion. During the explosion, a ~10% anisotropy in the low-mass,high-velocity ejecta lead to recoil of the high-mass neutron star. At the endof our simulation, the NS has achieved a velocity of ~150 km s$^{-1}$ and isaccelerating at ~350 km s$^{-2}$, but has yet to reach the ballistic regime.The recoil is due almost entirely to hydrodynamical processes, with anisotropicneutrino emission contributing less than 2% to the overall kick magnitude.Since the observed distribution of neutron star kick velocities peaks at~300-400 km s$^{-1}$, recoil due to anisotropic core-collapse supernovaeprovides a natural, non-exotic mechanism with which to obtain neutron starkicks.
