  We construct a new holographic description of QCD using domain wall fermions.
The construction consists of probe D7 branes in a D5 brane geometry describing
quarks on a 4+1d defect in a 5+1d gauge theory. We then compactify one
dimension of the D5 to introduce confinement in the gauge degrees of freedom.
In addition we allow a spatial dependent mass term for the D7 brane quarks to
isolate chiral fermions on 3+1d domain walls. The D7 world volume fields, when
restricted to the domain wall position, provide an AdS/QCD description. We
compute the spectrum and compare to data. We include higher dimension operators
to systematically improve the description.
