Type II string theory compactified on a Calabi-Yau manifold, with a singularity modeled by a hypersurface in an orbifold, is considered. In the limit of vanishing string coupling, one expects a non gravitational theory concentrated at the singularity. It is proposed that this theory is holographicly dual to a family of ``non-critical'' superstring vacua, generalizing a previous proposal for hypersurfaces in flat space. It is argued that a class of such singularities is relevant for the study of non-trivial IR fixed points that appear in the moduli space of four-dimensional N=2 SQCD: SU(Nc) gauge theory with matter in the fundamental representation. This includes the origin in the moduli space of the SU(Nc) gauge theory with Nf=2Nc fundamentals. The 4D IR fixed points are studied using the anti-holographic description and the results agree with information available from gauge theory.
