Abstract In this paper, a new class of sets called delta generalized pre-closed sets in topological spaces is introduced and some of their basic properties are investigated. This new class of sets lies between the class of gp- closed sets and the class of gpr-closed sets. Further the notions of δgp- neighbourhood, δgp-closure and δgp-interior are introduced and their properties are discussed. Several examples are provided to illustrate the behavior of new sets.
