AB - In this paper, the definition of α-interval valued fuzzy subgroup is  introduced by the help of α-interval valued fuzzy set which is constructed  on α-interval valued set whose elements are closed sub-intervals including α  of unit interval I = [0, 1]. The fundamental and structural properties of  these groups are examined. Some definitions, propositions and examples about  these groups are given.
