  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.
