Due to importance of the concepts of ${ heta}$-closure and ${delta}$-closure, it is natural to try for their extensions to fuzzy topological spaces. So, Ganguly and Saha introduced and investigated the concept of fuzzy ${delta}$-closure by using the concept of quasi-coincidence in fuzzy topological spaces. In this paper, we will introduce the concept of ${delta}$-closure in intuitionistic fuzzy topological spaces, which is a generalization of the ${delta}$-closure by Ganguly and Saha.
