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 {ital G}/{ital G}{sub 0} (where {ital G} is the conductance of the junction and {ital G}{sub 0}=2{ital e}{sup 2}/{ital h}). The enhanced backscattering can be detected by means of ballistic point contacts.
