Add to ORKGIn this paper, the strong product of two graphs G1 & G2 which are hyperbolic is studied. The strong product G1⊠G2 is hyperbolic if and only if one of the factors is hyperbolic and the other one is bounded. Furthermore, we obtained the exact values of the hyperbolicity constant for many strong product graphs
