The \cal N=1 SUSY nonlinear sigma models in four spacetime dimensions are studied to obtain BPS walls and junctions. A nonlinear sigma model with a single chiral scalar superfield is found which has a moduli space of the topology of S1 and admits BPS walls and junctions connecting arbitrary points in moduli space. New BPS junction solutions connecting N discrete vacua are also found for nonlinear sigma models with several chiral scalar superfields. More detailed exposition of our results can be found in Ref.\citeNNS.
