We find new supersymmetric backgrounds of {\cal N} = 8 gauged supergravity in four Euclidean dimensions that are dual to deformations of ABJM theory on S^3. The deformations encode the most general choice of U(1)_R symmetry used to define the theory on S^3. We work within an {\cal N} = 2 truncation of the {\cal N} = 8 supergravity theory obtained via a group theory argument. We find perfect agreement between the S^3 free energy computed from our supergravity backgrounds and the previous field theory computations of the same quantity based on supersymmetric localization and matrix model techniques.
