In this paper, a new technique, namely, the New Homotopy Perturbation Method (NHPM) is applied for solving a non-linear two-dimensional wave equation. The two most important steps in application of the new homotopy perturbation method are to construct a suitable homotopy equation and to choose a suitable initial guess. Comparison between our solution with Homotopy perturbation method (HPM) shows that the NHPM is effective and accurate in solving these kinds of equation.
