The Wiener polarity index W p (G) of a graph G = (V , E) is the number of unordered pairs of vertices {u, v} of G such that the distance d G (u, v) between u and v is 3. In this work, we give the maximum Wiener polarity index of trees with n vertices and k pendants and find that the maximum value is
