A fan-out semiconductor package includes a first connection member having a through-hole, a semiconductor chip disposed in the through-hole, a first encapsulant encapsulating at least portions of the first connection member and the semiconductor chip, a second connection member disposed on the first connection member and the semiconductor chip. The first connection member and the second connection member respectively include redistribution layers electrically connected to the connection pads of the semiconductor chip. The fan-out semiconductor package may have excellent rigidity, may be thinned, and may be manufactured in a simplified process.
