We find and analyze the Landau-Ginzburg potentials whose critical points determine chiral rings which are exactly the fusion rings of S P (N) K WZW models. The quasihomogeneous part of the potential associated with S P (N) K is the same as the quasihomogeneous part of that associated with SU (N+1) K , showing that these potentials are different perturbations of the same Grassmannian potential. Twisted N=2 topological Landau-Ginzburg theories are derived from these superpotentials. The correlation functions, which are just the S P (N) K Verlinde dimensions, are expressed as fusion residues. We note that the S P (N) K and S P (K) N topological Landau-Ginzburg theories are identical, and that while the SU (N) K and SU (K) N topological Landau-Ginzburg models are not, they are simply related.
