Abstract: An analysis has been carried out to Numerical study of MHD boundary layer stagnation point flow and heat transfer over an exponentially stretching surface with thermal radiation. The coupled partial differential equations are reduced into ordinary differential equations by similarity transformations. Numerical solutions of the coupled non-linear system is obtained by using shooting technique namely known as Runge-Kutta method. The convergence salient features of the flow and heat transfer characteristics are analyzed and discussed in detail through graphs .The variation of pradntl number, Grashoff number, Eckert number are discussed in detail, comparison of the present results with known numerical results of stagnation point flow and thermal radiation is made excellent agreement is noted. Applications are used in engineering process such as extraction of polymer sheet, paper production, glass fiber production and chemical engineering systems.

Keywords: Boundary layer flow, exponentially stretching sheet, Numerical solution, Thermal Radiation.
