The invention provides a vehicle body rear side wall structure and a vehicle, and relates to the technical field of automobile manufacturing. The automobile body rear side wall structure comprises a C/D column assembly, a top cover rear cross beam, a rear connecting plate assembly, a hat and coat stand assembly, a rear wall assembly, a floor assembly and a floor cross beam. The top cover rear cross beam is connected between the C/D column assemblies on the two sides, the top ends of the rear connecting plate assemblies on the two sides are connected to the top ends of the rear sides of the C/D column assemblies on the two sides respectively, the hat and coat stand assembly is connected between the C/D column assemblies on the two sides, and the rear wall assembly is connected between the rear tail ends of the rear connecting plate assemblies on the two sides. The floor assembly is connected between the bottom ends of the C/D column assemblies on the two sides and the bottom ends of the rear connecting plate assemblies on the two sides, and the floor cross beam is arranged on the floor assembly and connected between the C/D column assemblies on the two sides. According to the vehicle body rear side wall structure, the multiple annular frame structures which are connected and supported are designed, a complete force transmission path is achieved, the continuity and integrity of the rear side wall structure are enhanced, and the torsional rigidity, the torsional mode and the NVH performance of a vehicle are improved.
