Intersection digraphs analogous to undirected intersection graphs are introduced. Each vertex is assigned an ordered pair of sets, with a directed edge uu in the intersection digraph when the "source set" of u intersects the "terminal set" of u. Every n-vertex digraph is an intersection digraph of o
