The Wiener polarity index WP(G) of a graph G=(V,E) is the number of unordered pairs of vertices {u,v} of G such that the distance dG(u,v)=3. In this paper, the minimum (resp. maximum) Wiener polarity index of trees with n vertices and maximum degree Δ are given, and the corresponding extremal trees are determined, where 2≤Δ≤n−1. Moreover, the trees minimizing WP(T) among all trees T of order n and k leaves are characterized, where 2≤k≤n−1.
