The invention relates to a D column connecting structure and a vehicle. The D column connecting structure comprises a rear wall outer plate, two rear wall connecting plates, two rear wall sealing plates and two rear floor longitudinal beam assemblies. Each rear wall connecting plate comprises a first folded plate and a second folded plate which are connected with each other, and the first folded plate and the second folded plate are arranged at an included angle, so that the rear wall outer plate, the first folded plate and the second folded plate are enclosed together and jointly used for connecting a D column; one end of the rear floor longitudinal beam assembly is connected to the rear wall outer plate, and the rear floor longitudinal beam assembly and the outer plate flanging part are located on the same side of the rear wall outer plate; the rear wall sealing plate is connected with the rear wall connecting plate and the rear floor longitudinal beam assembly and covers the outer surface of part of the rear wall connecting plate and the outer surface of part of the rear floor longitudinal beam assembly, and the rear wall sealing plate, the rear wall connecting plate and the rear floor longitudinal beam assembly are enclosed in a cavity mode. The D column connecting structure has the advantages that the rigidity of the lap joint position of the D column and the rear floor longitudinal beam assembly is improved, so that the NVH performance, safety and comfort of a vehicle body are improved.
