The present disclosure discloses a folding chair comprising a seat plate, a back plate, two front legs, and two rear legs. Each of the two front legs is connected with a joint. The joint is disposed between the back plate and the seat plate, and the joint extends rearward to form an extension portion. A rear end of the extension portion is rotatably connected to a top end of a corresponding one of the two rear legs, and a barrier extends from a rear edge of each of the two front legs or a front edge of each of the two rear legs. When the folding chair is folded, the barrier separates each of the two front legs from a corresponding one of the two rear legs and provides an accommodation space for fingers between each of the two front legs and the corresponding one of the two rear legs.
