A collapsible suitcase has a bottom panel, a rear panel, two side panels, and a front panel. The rear panel, side panels, and front panel are connected to the bottom panel by hinges permitting them to be rotated from a folded position against the bottom panel to a deployed position perpendicular to the bottom panel. The side hinges have a clearance sufficiently greater than the clearance of the front hinge to allow the side hinges to lie flat on the front panel when folded, and the rear hinge has a sufficiently greater clearance than that of the side hinges to allow the rear panel to lie flat on the side panels when folded.
