  We present a supersymmetric version of a two-field relaxion model that
naturalizes tuned versions of supersymmetry. This arises from a relaxion
mechanism that does not depend on QCD dynamics and where the relaxion potential
barrier height is controlled by a second axion-like field. During the
cosmological evolution, the relaxion rolls with a nonzero value that breaks
supersymmetry and scans the soft supersymmetric mass terms. Electroweak
symmetry is broken after the soft masses become of order the supersymmetric
Higgs mass term and causes the relaxion to stop rolling for superpartner masses
up to $\sim 10^9$ GeV. This can explain the tuning in supersymmetric models,
including split-SUSY models, while preserving the QCD axion solution to the
strong CP problem. Besides predicting two very weakly-coupled axion-like
particles, the supersymmetric spectrum may contain an extra Goldstino, which
could be a viable dark matter candidate.
