    Abstract: In this study, we discuss the product of bipolar, interval valued fuzzy graphs concept and
we give some properties for them. We will study some corollaries on Cartesian product and define some
properties on it. Tensor product, lexicographic product of bipolar interval valued fuzzy graph will also be
defined.
