We reexamine the dipole electric moment of the neutron {ital d}{sub {ital n}} in supersymmetric theories. We reassess the contributions to {ital d}{sub {ital n}} from Weinberg's gluonic operator and the color and electric dipole operators, emphasizing the proper evaluation of their QCD correction factors, and see that {ital d}{sub {ital n}} is a very sensitive probe of these theories. We also give a calculation of the phrase that determines {ital d}{sub {ital n}} in realistic models and conclude that the dominant contribution to {ital d}{sub {ital n}} is expected to be due to strong (and not weak) {ital CP}-violating effects.
