Let GF(q) denote the finite field with q elements. The Paley graph Paley(q) is defined to be a graph with vertex set GF(q) such that two vertices a and b are joined with an edge if a-b is a non-zero square. If we assume q≡1(mod4) , then this graph is undirected. In this paper, our aim is to compute the topological indices of Paley(q) such as the Wiener, PI and Szeged indices of this graph.
