Renormalization group methods are used to determine the evolution of the low energy Wilson effective action for supersymmetric nonlinear {sigma} models in four dimensions. For the case of supersymmetric CP{sup N{minus}1} models, the K{umlt a}hler potential is determined exactly and is shown to exhibit a nontrivial ultraviolet fixed point in addition to a trivial infrared fixed point. The strong coupling behavior of the theory suggests the possible existence of additional relevant operators or nonperturbative degrees of freedom. {copyright} {ital 1997} {ital The American Physical Society}
