Coherent elastic neutrino-nucleus scattering (CEvNS) is a process in

which a neutrino scatters off an entire nucleus. It is tremendously

challenging to detect, due to the tiny nuclear recoil. CEvNS was

measured for the first time by the COHERENT collaboration using the

unique source of neutrinos at the Oak Ridge National Laboratory

Spallation Neutron Source.  This talk will describe the physics reach

of CEvNS, as well as COHERENT's measurements, status and future plans.
