We report preliminary results for charmonium-nucleon potential V{sub cc}-bar{sub N}(r) from quenched lattice QCD, which is calculated from the equal-time Bethe-Salpeter amplitude through the effective Schroedinger equation. Our simulations are performed at a lattice cutoff of 1/a = 2.0 GeV in a spatial volume of (3 fm){sup 3} with the nonperturbatively O(a) improved Wilson action for the light quarks and a relativistic heavy quark action for the charm quark. We have found that the potential V{sub cc}-bar{sub N}(r) is weakly attractive at short distance and exponentially screened at long distance.
