  We explore the prospects of constraining general non standard interactions
involving light mediators through elastic neutrino-electron scattering events
at the DUNE Near Detector (ND). We furthermore consider the special cases of
light vector mediators in motivated models such as $U(1)_{B-L}$, $U(1)_{L_\mu -
L_\tau}$, $E_6$ and left-right symmetry. The present analysis is based on
detailed Monte Carlo simulations of the expected DUNE-ND signal taking into
account detector resolution effects, realistic backgrounds as well as On-Axis
and Off-Axis neutrino spectra. We show that the high intensity neutrino beam
available at Fermilab can place competitive constraints surpassing those of
low-energy neutrino searches and direct detection dark matter experiments.
