The invention discloses a child stroller with an adjustable backrest angle. The child stroller comprises a stroller frame. The seat part is arranged on the frame; the backrest is connected to the seat part or the frame, the backrest can rotate around a first rotating axis to adjust the inclination angle relative to the seat part, and a sliding groove is formed in the backrest in the height direction; the rocker is rotatably connected to the frame around a second rotation axis parallel to the first rotation axis, the rocker comprises a limiting section arranged in the sliding groove in a penetrating mode, and the limiting section is parallel to and deviates from the second rotation axis; the backrest has a sitting position and a lying position, the limiting section is located below the second rotating axis in the vertical direction at the sitting position, and the included angle between the plane where the limiting section and the second rotating axis are located and the horizontal plane is larger than or equal to 10 degrees. The rotating angle of the backrest is locked and limited through the matching relation between the sliding groove and the rocker, operation is convenient, cost is reduced, and the structure is lighter.
