In this talk I will discuss the possibility of unveiling new physics with neutrino and dark matter experiments, highlighting a strong complementarity among different facilities. I will focus on two different examples.  First I will reconsider the discovery limit of multi-ton direct detection dark matter experiments in the light of recent measurements of the coherent elastic neutrino-nucleus scattering process by the COHERENT experiment. I will further comment about the impact of subleading nuclear form factor uncertainties, weak mixing angle uncertainties and new physics effects on the neutrino floor.  A precise understanding of WIMP discovery limits is indeed required for a correct interpretation of forthcoming data from multi-ton dark matter direct detection experiments. Secondly, I will discuss the possibility of detecting dark matter in the form of light primordial black holes (PBHs) with future neutrino experiments DUNE and THEIA. I will show that these facilities will be able to set competitive constraints on PBH dark matter, thus providing complementary probes in a part of the PBH parameter space currently constrained mainly by photon data.
