In this talk we present results of the V_low k Renormalization Group (RG) method applied to Hyperon-Nucleon systems. Recently this method has been successfully applied to Nucleon-Nucleon (NN) systems by the Stony Book group. They obtained a unique low momentum NN potential.

We start with a brief introduction to V_low k and explain the basics of the method. In the following we apply the method to the YN-systems, using realistic Nijmegen Hyperon-Nucleon potentials as starting point. Although the Nijmegen models are quite different we also see a convergence to a unique YN V_low k.
