We construct anomaly-free nonsupersymmetric large {ital N} gauge theories from orientifolds of type IIB on {bold C}{sup 3}/{Gamma} orbifolds. In particular, massless as well as tachyonic one-loop tadpoles are canceled in these models. This is achieved by starting with N=1,2 supersymmetric orientifolds with a well defined world-sheet description and including discrete torsion (which breaks supersymmetry) in the orbifold action. In this way we obtain nontrivial nonchiral as well as anomaly-free chiral large {ital 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 {ital M}-point correlation function in these theories reduces to the corresponding computation in the parent N=4 oriented theory. This generalizes the analogous results recently obtained in supersymmetric large {ital N} gauge theories from orientifolds, as well as in (non)supersymmetric large {ital N} gauge theories without orientifold planes. {copyright} {ital 1999} {ital The American Physical Society}
