Supersymmetry is the most promising new physics beyond the Standard Model (SM). However, the naturalness in the Supersymmetric SMs (SSMs) is challenged from both the SM-like Higgs boson mass and the LHC supersymmetry searches. We point out that the electroweak fine-tuning problem in the SSMs is mainly due to the high energy definition of the fine-tuning measure. We propose the super-natural supersymmetry which has an order one high energy fine-tuning measure automatically. The key point is that all the mass parameters in the SSMs arise from a single supersymmetry breaking parameter. Considering no-scale supergravity and Giudice-Masiero mechanism, we show explicitly that the high energy fine-tuning measure is indeed of unit order in the F-SU(5) and Minimal SSM (MSSM). In addition, we study the M-theory inspired the Next to MSSM (NMSSM) since the NMSSM can be scale invariant and is the perfect framework for super-natural supersymmetry. Furthermore, we propose the effective super-natural supersymmetry and realize it in the SSM with Dirac gauginos and gauge mediation.
