The foldable trolley comprises a foldable trolley frame and wheels installed at the bottom of the trolley frame, the trolley frame has the transverse direction and the longitudinal direction which are opposite, and the trolley frame comprises two side frames arranged oppositely and a transverse connecting piece connected between the two side frames. The two side frames and the transverse connecting pieces integrally define a cage-shaped structure with the top open, and the interior of the cage-shaped structure is a bearing area. The side frame adopts a foldable four-bar mechanism, in an unfolded state, four bar pieces are hinged in sequence, two of the bar pieces are horizontally arranged and located at the bottom edge of the side frame, and the other two bar pieces extend upwards, intersect and are hinged with each other; in the folding state, all rod pieces in the four-bar mechanism are gathered together. Compared with an existing trolley, the lower portion of an original seat is transformed into a cage-shaped structure for bearing children or loading objects so as to improve the storage capacity, only one four-connecting-rod mechanism is arranged, and the trolley is simple in structure, stable and reliable.
