The invention discloses a baby stroller capable of being folded in the center. The baby stroller comprises a front foot pipe, a rear foot pipe, a handle pipe, a supporting pipe and a seat rod. The lower end of the handle pipe and the upper end of the front foot pipe are locked or unlocked for rotation through a rotating joint, the upper end of the supporting pipe is rotatably connected with the handle pipe, the lower end of the supporting pipe is rotatably connected with the rear foot pipe, and the middle section of the seat rod is rotatably connected with the rear foot pipe. When the baby stroller folded in the center is unfolded, a connecting piece and a seat rod are basically located on the same straight line, and the connecting piece, the seat rod, the front foot pipe and the rear footpipe form a triangular frame structure. When the baby stroller folded in the center is folded, the connecting piece, the seat rod, the front foot pipe and the rear foot pipe form a quadrilateral frame structure. The baby stroller further comprises a linkage piece which is arranged on the seat rod and can be used for unlocking the rotating joint in an operable mode. After operation of a connectingrod structure composed of the connecting piece, the seat rod, the front foot pipe and the rear foot pipe and the linkage piece, the structural stability during unfolding is improved, and auxiliary folding is easy during folding.
