In this paper, we introduce the concepts of fuzzy upper and fuzzy lower almost e *-continuous multifunctions on fuzzy topological spaces in Ŝ ostak’s sense. Several characterizations and properties of these fuzzy upper (resp. fuzzy lower) almost e* - continuous multifunctions are presented and their mutual relationships are established in L -fuzzy topological spaces. Later, composition and union between these multifunctions have been studied.
