Given an undirected multigraph G and a set $\mathcal{S}:=\{S_{1},...,S_{t}\}$ of disjoint subsets of vertices of G, a Steiner $\mathcal{S}$-forest F is an acyclic subgraph of G such that each Si is connected in F for 1 ≤ i ≤ t. In this paper, we study the Steiner Forest Packing problem where we seek a largest collection of edge-disjoint $\mathcal{S}$-forests. The main result is a connectivity-type sufficient condition for the existence of k edge-disjoint $\mathcal{S}$-forest, that yields the first polynomial time approximation algorithm for the Steiner Forest Packing problem. We end this paper by a conjecture in a more general setting.
