We determine that the connectivity and the edgeconnectivity of the Cartesian product G 1 × G 2 of two strongly connected and finite digraphs G 1 and G 2 are equal to min{n 1 κ 2 , n 2 κ 1 , δ are the order, the connectivity, the edgeconnectivity, the minimum out-degree and the minimum in-degree of G i , respectively, for i = 1, 2.
