The interaction of quarkonium with nuclei is studied in the mQ→ ∞ limit of QCD, where the binding energy is found to be exactly computable. The dominant contribution to the interaction is from two-gluon operators. The forward matrix elements of these two-gluon operators can be determined from the QCD scale anomaly, and from deep inelastic scattering. We apply our results to the Υ and J/ψ, treating the \qqbar interaction as purely Coulombic. We find the Υ binds in nuclear matter with a binding energy of a few \mev, while for the J/ψ binding is of order 10 \mev. For the J/ψ in particular we expect confinement effects to produce large corrections to this result.
