  The present status of neutrino cross section physics is reviewed focusing on
the recent theoretical developments in quasielastic scattering, multi-nucleon
contributions to the inclusive scattering and pion production on nucleons and
nuclei. A good understanding of these processes is crucial to meet the
precision needs of neutrino oscillation experiments. Some of the challenges
that arise in the consistent description of MiniBooNE and MINERvA recent data
are discussed.
