It is shown analytically and by numerical simulation that the angular distribution of Andreev reflection by a disordered normal-metal--superconductor junction has a narrow peak at the angle of incidence. The peak is higher than the well-known coherent backscattering peak in the normal state, by a large factor G/G0 (where G is the conductance of the junction and G0=2e2/h). The enhanced backscattering can be detected by means of ballistic point contacts.
