We propose an electric-magnetic duality and conjecture an exact conformal window for a class of nonsupersymmetric U(N-c) gauge theories with fermions in the (anti)symmetric representation of the gauge group and Nf additional scalar and fermion flavors. The duality exchanges N-c -> N-f - N-c --/+ 4 leaving Nf invariant, and has common features with Seiberg duality in N = 1 super QCD (SQCD) with SU or SO/Sp gauge group. At large N the duality holds due to planar equivalence with N = 1 SQCD. At finite N we embed these gauge theories in a setup with D-branes and orientifolds in a nonsupersymmetric, but tachyon-free, noncritical type OB string theory and argue in favor of the duality in terms of boundary and crosscap state monodromies as in analogous supersymmetric situations. One can verify explicitly that the resulting duals have matching global anomalies. Finally, we comment on the moduli space of these gauge theories and discuss other potential nonsupersymmetric examples that could exhibit similar dualities.
