In this paper, delta-lifting and delta-supplemented modules are defined as generalizations of lifting and supplemented modules. Several properties of these modules are proved. New characterizations of delta-semiperect and delta-perfect rings studied in  are obtained using delta-lifting and delta-supplemented modules.
