The notion of intuitionistic fuzzy sets was introduced by Atanassov as a generalization of the notion of fuzzy sets. In this paper, we apply this concept to Gamma - semihypergroups and we introduce the notion of an intuitionistic fuzzy Gamma - hyperideal of a Gamma - semihypergroup. Then, we investigate some properties connected with intuitionistic fuzzy Gamma - hyperideals in a Gamma - semihypergroup.
