In this paper, we introduce the notion of an implicative vague filter in BE-algebras, and investigate some properties of them. Also we give conditions for a vague set to be an implicative vague filter, and we characterize implicative vague filters in BE-algebras. We define the notion of <TEX>$n$</TEX>-fold implicative vague filters in BE-algebras and we give characterizations of <TEX>$n$</TEX>-fold implicative vague filters and <TEX>$n$</TEX>-fold implicative BE-algebras.
