  A supersymmetric (SUSY) model of radius stabilization is constructed for the
S^1/Z_2 warped compactifications with a hypermultiplet in five dimensions.
Requiring the continuity of scalar field across the boundaries, we obtain
radius stabilization preserving SUSY, realizing the SUSY extension of the
Goldberger-Wise mechanism. Even if we allow discontinuities of the Z_2 odd
field across the boundary, we always obtain SUSY preservation but obtain the
radius stabilization only when the discontinuity is fixed by other mechanism.
