Algebraic hyperstructures represent a natural extension of classical algebraic structures. One of the classes of algebraic hyperstructures is the class of Gamma-semihypergroups. In this paper, we investigate the notion of fuzzy interior Gamma-hyperideal of a Gamma-semihypergroup and investigate some of their properties.
