## Abstract :

In this paper, the concepts of fuzzy supra β-nowhere dense set, fuzzy supra β-first category set and fuzzy supra β-second category set in fuzzy supra topological spaces are introduced and studied. By means of fuzzy supra β-nowhere dense sets, the concept of fuzzy supra β-Baire space is defined and several characterizations of fuzzy supra β-Baire spaces are studied.
