The vehicle side wall connecting structure comprises a top edge beam inner plate, a top edge beam reinforcing plate, a C-ring upper connecting piece, a transverse reinforcing piece, a D-column inner plate and a D-column reinforcing plate, wherein the top edge beam reinforcing plate, the C-ring upper connecting piece, the transverse reinforcing piece, the D-column inner plate and the D-column reinforcing plate are fixedly connected to the top edge beam inner plate. A top edge beam cavity is defined by the top edge beam inner plate and the top edge beam reinforcing plate, a C-ring cavity is defined by the top edge beam inner plate and the C-ring upper connecting piece, a transverse reinforcing cavity is defined by the top edge beam inner plate and the transverse reinforcing piece, and a D-column cavity is defined by the top edge beam inner plate, the D-column inner plate and the D-column reinforcing plate. The top edge beam cavity is adjacent to the C-ring cavity, the C-ring cavity is adjacent to the transverse reinforcing cavity, the transverse reinforcing cavity is adjacent to the D-column cavity, and the D-column cavity is adjacent to the top edge beam cavity; the outer wall of the top edge beam cavity, the outer wall of the C-ring cavity, the outer wall of the transverse reinforcing cavity and the outer wall of the D-column cavity define an annular reinforcing part. According to the vehicle side wall connecting structure, the torsional rigidity of the vehicle body can be remarkably improved, and then the NVH performance of the vehicle is improved.
