  In the framework of the Instanton Liquid Model we evaluate the heavy quark
$\bar{Q}Q$ potential at nonzero temperature $T$. The potential has two
components: contribution due to direct interaction with instantons, and the
modification of the one-gluon exchange contribution via instanton-generated
dynamical \char`\"{}electric\char`\"{} gluon mass $M_{el}(q,T)$. We conclude
that the nonperturbative ILM contributions to the $Q\bar{Q}$ potential have
pronounced temperature dependence, which might be tested in phenomenological
analyses of charmonia production data.
