Disclosed are a rear floor structure, a rear casting of the rear floor structure, and a vehicle. The rear floor structure comprises a rear floor front section assembly (1) and a rear casting (2). An accommodating space for accommodating the rear floor front section assembly is formed at the front end of the rear casting, two transverse sides of the rear casting are respectively connected to sill beams (3, 4) on two sides, and the bottom of the rear floor front section assembly is provided with a first sealing surface (A) used for forming a seal with a battery pack assembly, the bottom of each sill beam is provided with a second sealing surface (B) used for forming a seal with the battery pack assembly, there is a height difference between the first sealing surface and the second sealing surface, sealing reinforcement structures are arranged at the joint of the rear casting and the sill beam, a transition sealing surface (C) is formed on the sealing reinforcement structures, and the transition sealing surface is in smooth butt-joint with the first sealing surface and the second sealing surface in the transverse direction. According to the rear floor structure, the sealing surface of the rear floor is in smooth butt-joint with the sealing surface of the sill beam to form a continuous sealing surface, and a plurality of sealing reinforcement structures can be arranged in the longitudinal direction to adapt to vehicles of different wheelbases, so as to realize platform universalization.
