The purpose of the present problem is to study the effect of Rotation on MHD flow of visco-elastic (Rivlin-Ericksen) fluid through porous medium with transpiration. The governing equations of motions are solved by a regular perturbation technique. The velocity of fluid, skin friction, temperature and concentration are discussed with the help of tables and graphs. The primary velocity of fluid increases with the increase in M (Hartman number), but it decreases with the increase in Gr (Grashof Number), K (Porosity parameter) and  (Rotation parameter). The secondary velocity increases with the increase in Gr, M and , but it decreases with the increase in K.
