  We study the production of scalar leptoquarks at IceCube, in particular, a
particle transforming as a triplet under the weak interaction. The existence of
electroweak-triplet scalars is highly motivated by models of grand unification
and also within radiative seesaw models for neutrino mass generation. In our
framework, we extend the Standard Model by a single colored electroweak-triplet
scalar leptoquark and analyze its implications on the excess of ultra-high
energy neutrino events observed by the IceCube collaboration. We consider only
couplings between the leptoquark to first generation leptons and quarks and
carry out a statistical analysis to determine the parameters that best describe
the IceCube data as well as set $95\%$ CL upper bounds. We analyze whether this
study is still consistent with most up-to-date LHC data and various low energy
observables.
