  We construct a large family of Euclidean supersymmetric wormhole solutions of
type IIB supergravity which are asymptotically AdS$_5 \times S^5$. The
solutions are constructed using consistent truncation to maximally gauged
supergravity in five dimensions which is further truncated to a four scalar
model. Within this model we perform a full analytic classification of
supersymmetric domain wall solutions with flat Euclidean domain wall slices. On
each side of the wormhole, the solution asymptotes to AdS$_5$ dual to ${\cal
N}= 4$ supersymmetric Yang-Mills deformed by a supersymmetric mass term.
