We construct an extension of the minimal supersymmetric standard model in which superpartners can naturally be heavier than the electroweak scale. This 'little hierarchy' of scales is stable because the Higgs arises as a pseudo-Nambu-Goldstone boson in the breaking of an accidental SU(4) symmetry of the Higgs sector. Supersymmetry and the global symmetry combine to forbid logarithmically divergent one-loop contributions to the Higgs mass. The accidental symmetry follows from a simple twin parity which exchanges the SU(2) sectors in the SU(3){sub C}xSU(2){sub L}xSU(2){sub R}xU(1){sub X} gauge group.
