We examine contributions from Majorana phases to lepton flavor violating processes in the framework of the minimal supersymmetric standard model with heavy right-handed neutrinos. All phases in the complex neutrino Yukawa matrix are taken into account in our study. We find that in the scenario with universal soft-breaking terms sizable phase effects can appear on the lepton flavor violating processes such as {mu}{yields}e{gamma}, {tau}{yields}e{gamma}, and {tau}{yields}{mu}{gamma}. In particular, the branching ratio of {mu}{yields}e{gamma} can be considerably enhanced due to the Majorana phases, so that it can be much greater than that of {tau}{yields}{mu}{gamma}.
