  We construct a gravitational dual of the pseudo-conformal universe, a
proposed alternative to inflation in which a conformal field theory in nearly
flat space develops a time dependent vacuum expectation value. Constructing
this dual amounts to finding five-dimensional domain-wall spacetimes with
anti-de Sitter asymptotics, for which the wall has the symmetries of
four-dimensional de Sitter space. This holographically realizes the
characteristic symmetry breaking pattern O(2,4) to O(1,4) of the
pseudo-conformal universe. We present an explicit example with a massless
scalar field, using holographic renormalization to obtain general expressions
for the renormalized scalar and stress-tensor one-point functions. We discuss
the relationship between these solutions and those of four-dimensional
holographic defect conformal field theories which break O(2,4) to O(2,3)
