In this paper we introduced the concept of complementary super edge magic labeling and Complementary Super Edge Magic strength of a graph G.A graph G (V, E ) is said to be complementary super edge magic if there exist a bijection f:V U E → { 1, 2, …………p+q } such that p+q+1 - f(x) is constant. Such a labeling is called complementary super edge magic labeling with complementary super edge magic strength. In this paper for a graph G(V, E ) the complementary super edge magic labeling and minimum of all constants which is called complementary super edge magic strength of G is defined. In this paper, we investigate whether some families of graphs are complementary or not?
