Abstract: An upper bound for Weiltype exponential sums over Galois rings is presented together with some examples where the bound is tight. The bound may be regarded as the Galoisring analogue of the wellknown WeilCarlitzUchiyama bound for exponential sums over finite fields. An application of the bound to the design of large families of eightphase sequences having low correlation is also given.
