The invention discloses a stroller which comprises a bottom supporting frame and a seat supporting frame. The bottom supporting frame comprises front legs and rear legs, and wheel assemblies are arranged on the front legs and the rear legs. A supporting rod is rotationally connected to the bottom supporting frame. A first transmission assembly capable of driving the front legs to rotate and approach the rear legs is arranged between the supporting rod and the front legs. A second transmission assembly capable of driving the seat supporting frame to rotate towards the front legs and draw close to the front legs is arranged between the seat supporting frame and the bottom supporting frame. The second transmission assembly comprises a rack which is arranged on the front leg and can slide relative to the front leg. The rear legs are provided with gear parts which are meshed with the racks and enable the racks to slide relative to the front legs when the front legs rotate towards the rear legs to be folded. A traction component capable of driving the seat support frame to get close to the front legs when the rack slides is also arranged between the rack and the seat support frame. The invention aims to overcome the defects in the prior art, and provides the baby stroller which is convenient to fold and unfold, simple in structure and small in size after being folded.
