Abstract: Current and upcoming accelerator-based neutrino experiments will offer new sensitivity to the dark sector by involving the largest detectors and most intense proton beams. I will discuss several candidate dark sector models for which the leading sensitivity is found at neutrino experiments. The models I focus on include dark sector portals, boosted dark matter, and mesogenesis. I will present aspects of these models including their motivation in cosmology, the simulation of their signals, and the projected sensitivity of various neutrino experiments to these models. The work I present illustrates the power and complementarity of neutrino experiments such as those making up the Short-Baseline Neutrino Program, DUNE, Hyper-Kamiokande, and JUNO in enabling a discovery of new dark sector physics.
