Abstract: The characterizations of(*)-good congruence on superabundant semigroups are studied by means of(*)-Greens relation and the properties of superabundant semigroups. The sufficient and necessary condition that any two elements on a superabundant semigroup S are in the same(*)-good congruence class is given and the description of any congruence contained in D * on S is obtained.
