We initiate a program to apply eikonal methods in the AdS/CFT correspondence, probing the physics at finite values of the gravitational coupling G. We first review eikonal scattering in flat space, and the dominance of graviton exchange in certain kinematical regimes. We then extend the analysis to graviton exchange in AdS to all orders in G, by analyzing propagation in the presence of shock-wave geometries. We relate these results to statements in the dual CFT, regarding the expansion of the dual four point amplitude in conformal partial waves.
