A folding suitcase includes a back case component, a front lid component, a circumferential surface component, and a restoring component. Two opposite sides of the circumferential surface component are connected with the back case component and the front lid component, respectively, so as to form an accommodating space selectively. The circumferential surface component has multiple sidewall parts and multiple bending parts connected with the multiple sidewall parts. The multiple bending parts are bendable to lead the multiple sidewall parts to be capable of being folded oppositely or being erected on the back case component. The restoring component is located on at least one bending part. The restoring component is elastic for erecting the multiple sidewall parts.
