  Neutrino-nucleus coherent scattering measurements by the COHERENT
collaboration provide us with a unique capability to test various beyond the
standard model scenarios. In this work, we constrain scalar leptoquarks (LQs)
using the COHERENT data. LQs arise in many extensions of the Standard Model
(SM). Generally, the mass of the LQs is assumed to be very high to avoid the
bounds from proton decay. However, there are low-scale LQ models which prohibit
proton decay by construction. We consider two electroweak doublet scalar LQ
models with hypercharge Y=1/6, and Y=7/6 and provide the bounds in the plane of
the Yukawa coupling and the mass of LQ. We also compare the bounds on LQs
coming from various other experiments and find that the COHERENT one covers a
wide range of LQ masses from MeV to TeV and in certain regions the constraints
are competitive with the others.
