A thermodynamic analysis of viscoelastic magnetohydrodynamic flow over a stretching surface in the presence of heat and mass transfer is carried out. The velocity, temperature and concentration profiles are obtained analytically using the Kummer's functions and used to compute the entropy generation number. The effects of the magnetic parameter, the viscoelastic parameter, the Prandtl number, the heat source/heat sink parameter, the surface temperature parameter and the surface concentration parameter on velocity, temperature and concentration profiles are presented. The influences of the same parameters, the Hartman number, the dimensionless group parameters, the Reynolds number, the ratio of the dimensionless concentration difference to the dimensionless temperature difference and the constant parameter on the entropy generation number are discussed.
