In this paper we propose a new method for obtaining the exact solutions of theNavier-Stokes (NS) equations for incompressible viscous fluid in the light of the theory of simplified Navier-Stokes(SNS) equations developed by the first author. Using the present method we can find some new exact solu-tions as well as the well-known exact solutions of the NS equations. In illustration of its applications, we give a va-riety of exact solutions of incompressible viscous fluid flows for which NS equations of fluid motion are written inCartesian coordinates, or in cylindrical polar coordinates, or in spherical coordinates.
