Abstract: $J/\ensuremath{\Psi}$-nuclear bound state energies are calculated for a range of nuclei by solving the Proca (Klein-Gordon) equation. Critical input for the calculations, namely the medium-modified $D$ and ${D}^{*}$ meson masses, as well as the nucleon density distributions in nuclei, are obtained from the quark-meson coupling model. The attractive potential originates from the $D$ and ${D}^{*}$ meson loops in the $J/\ensuremath{\Psi}$ self-energy in the nuclear medium. It appears that $J/\ensuremath{\Psi}$-nuclear bound states should produce a clear experimental signature provided that the $J/\ensuremath{\Psi}$ meson is produced in recoilless kinematics.
