We consider BPS domain walls in four-dimensional N = 1 supersymmetric models with continuous global symmetry. Since the BPS equation is covariant under a global transformation, the solutions of the BPS walls also have global symmetry. The moduli space of the supersymmetric vacua in such models has non-compact flat directions, and complex BPS walls interpolating between two disjoint flat directions can exist. We examine this possibility in two models with global O(2) symmetry and construct the solutions of such BPS walls.
