  A thorough understanding of neutrino cross sections in a wide range of
energies is crucial for the successful execution of the entire neutrino physics
program. In order to extract neutrino properties, long-baseline experiments
need an accurate determination of neutrino cross sections within their
detector(s). Since very few of the needed neutrino cross sections across the
energy spectrum are directly measured, we emphasize the need for theoretical
input and indirect measurements such as electron scattering, which would
complement direct measurements. In this report we briefly summarize the current
status of our knowledge of the neutrino cross sections and articulate needs of
the experiments, ongoing and planned, at energies ranging from CEvNS and
supernova neutrino energies to the DUNE and atmospheric neutrino energies.
