  We construct anomaly free non-supersymmetric large N gauge theories from
orientifolds of Type IIB on C^3/G orbifolds. In particular, massless as well as
tachyonic one-loop tadpoles are cancelled in these models. This is achieved by
starting with ${\cal N}=1,2$ supersymmetric orientifolds with well defined
world-sheet description and including discrete torsion (which breaks
supersymmetry) in the orbifold action. In this way we obtain non-trivial
non-chiral as well as anomaly free chiral large N gauge theories. We point out
certain subtleties arising in the chiral cases. Subject to certain assumptions,
these theories are shown to have the property that computation of any M-point
correlation function in these theories reduces to the corresponding computation
in the parent ${\cal N}=4$ oriented theory. This generalizes the analogous
results recently obtained in supersymmetric large N gauge theories from
orientifolds, as well as in (non)supersymmetric large N gauge theories without
orientifold planes.
