A wind turbine rotor blade (1) with an airfoil (5) having a suction side (13) and a pressure side (15) is provided. The airfoil (5) comprises an inner airfoil portion (7) and an outer airfoil portion (6), where the inner airfoil portion (7) is comparatively thicker than the outer airfoil portion (6) and provided with vortex generators (21). The thickness of the inner airfoil portion (7) is between 30% and 80% of the inner airfoil portion's (7) chord length, and the vortex generators (21) are located at the suction side (13) of the inner airfoil portion (7) between 8% and 12% of the chord length, as measured from the leading edge (9) of the airfoil portion (7).
