A path in an edge-colored graph is called a rainbow path if the edges on it have distinct colors. For k=1, the rainbow-k-connectivity of a graph G, denoted by rc"k(G), is the minimum number of colors required to color the edges of G in such a way that every two distinct vertices are connected by at least k internally vertex-disjoint rainbow paths. In this paper, we study rainbow-k-connectivity in the setting of random graphs. We show that for every fixed integer d=2 and every k=
