In the absence of the Higgs mass term the Standard Model is classically scale invariant and therefore a natural theory. Motivated by this observation we propose a model of Dark Supersymmetry, where a supersymmetric dark sector is coupled to the classically scale invariant non-supersymmetric Standard Model through the Higgs portal. The Dark sector contains a mass scale that is protected against radiative corrections by supersymmetry, and the portal coupling mediates this scale to the Standard Model Higgs, resulting in a vacuum expectation value for the Higgs field and the usual electroweak symmetry breaking mechanism and fermion masses. The supersymmetric dark sector contains dark matter candidates, and we show that the observed dark matter abundance is generated for a natural choice of parameters, while avoiding the current experimental bounds on direct detection. Future experiments can probe this scenario if the dark sector mass scale is not too high.
