A fan-out semiconductor package includes: a frame including insulating layers, wiring layers, and connection via layers, and having a recess portion and a stopper layer disposed on a bottom surface of the recess portion; a semiconductor chip disposed in the recess portion; a resin layer disposed on an active surface of the semiconductor chip; an encapsulant covering at least portions of side surfaces of the semiconductor chip and the resin layer and filling at least portions of the recess portion; a first redistribution layer disposed on the resin layer and the encapsulant; first redistribution vias penetrating through the resin layer to fill via holes in the resin layer exposing at least portions of the connection pads and electrically connecting the connection pads and the first redistribution layer to each other; and a connection member disposed on the resin layer and the encapsulant and including one or more second redistribution layers.
