The invention discloses a folding cart which comprises a front wall assembly, a rear wall assembly, a bottom frame assembly and two side wall assemblies, and when the folding cart is in an unfolded state, the two side wall assemblies, the front wall assembly, the rear wall assembly and the bottom frame assembly define a containing space used for containing objects; the side wall assembly comprises two first connecting rod structures and a side wall connecting structure, and one sides of the two first connecting rod structures are connected with the side wall connecting structure; the first connecting rod structure comprises a first X-shaped connecting rod mechanism and two first horizontal pieces, and one ends of the two first horizontal pieces are hinged to the two sides of the upper end of the first X-shaped connecting rod mechanism correspondingly. The side wall connecting structure comprises a first upper fixing seat, a first lower fixing seat and a first connecting piece, and the two ends of the first connecting piece are connected with the first upper fixing seat and the first lower fixing seat respectively. According to the side wall assembly, the first connecting piece is arranged in the side wall connecting structure, the first upper fixing base and the first lower fixing base are connected, and therefore the structural strength of the side wall assembly is improved.
