Abstract. The aim of the article is to generalize the notion of nowhere dense set with respect to a cluster topological space which is defined as a triplet where is a topological space and is a nonempty family of nonempty subsets of . The notions of -nowhere dense and locally -scattered sets are introduced and the necessary and sufficient conditions under which the family of all -nowhere dense sets is an ideal are given.
