  Janus solutions are constructed in $d=3$, ${\cal N}=8$ gauged supergravity.
We find explicit half-BPS solutions where two scalars in the $SO(8,1)/SO(8)$
coset have a nontrivial profile. These solutions correspond on the CFT side to
an interface with a position-dependent expectation value for a relevant
operator and a source which jumps across the interface for a marginal operator.
