A wind turbine blade includes a trailing edge flap having a flap part protruding from the trailing edge on the pressure side of the blade. The flap part has a first section and a second section each having an upstream surface arranged to face an oncoming airflow in use. The first section extends from the trailing edge and has a proximal end and a distal end in cross-section. The proximal end is located at or near the trailing edge and the distal end is spaced apart from the trailing edge. The first section is oriented such that an obtuse angle is defined between the upstream surface of the first section and a plane that extends parallel to the local chordal plane and intersects the proximal end of the first section. The second section is oriented such that the upstream surfaces of the first and second sections together define a concave profile in cross section.
