Abstract: I first motivate why we may want to look at possible new physics contributions to epsilon' given relatively clear experimental but unclear theoretical situations. I reexamine the supersymmetric contribution to epsilon' and find an important one generally missed in the literature. Based on rather model-independent arguments based on flavor symmetries, an estimate of the possible supersymmetric epsilon' is given, which interestingly come around the reported values without fine-tuning. If the observed values are dominated by supersymmetry, it is likely to give interesting consequences on hyperon CP violation, mu --> e+gamma, and neutron and electron electric dipole moments.
