As current and future neutrino oscillation experiments aim to complete our picture of neutrino mixing, they are already providing powerful constraints on new physics in the neutrino sector. At the same time, the first detection of coherent neutrino scattering on nuclei has opened a new area of research which is flourishing and evolving very rapidly. In this talk I will give an overview of new physics searches on these two fronts, highlighting the complementarity between the two. I will also provide an overview of possible avenues to search for the decay of new, light, feebly interacting particles in neutrino detectors, which may be produced either in the atmosphere or at the target station of neutrino facilities.
