The present status of neutrino cross section physics is reviewed fo-
cusing on the recent theoretical developments in quasielastic scattering,
multi-nucleon contributions to the inclusive scattering and pion produc-
tion 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 Mini-
BooNE and MINERvA recent data are discussed.
