A collapsible container includes a container body and a separate front wall combined together. The container body has a bottom wall and two sidewalls and a rear wall and an open front side and an open upper side. The two sidewalls and the rear wall may be collapsed to lie on the bottom wall by means of insert hooks provided at two ends of the rear wall and hook holes provided at a rear end of the two side walls. Then the collapsible container is easy to assemble, having small dimensions for easily storing and reducing cost for transporting when it is collapsed.
