[Solution] Provided is a vehicle rear portion structure 1 including a pair of rear frames 4 provided in the vehicle length direction and a rear floor panel 2 joined to the pair of rear frames 4, in which the rear floor panel 2 has a concave section 3 provided from the rear side of the vehicle toward the front side of the vehicle of the rear floor panel 2, and the concave section 3 is formed of a metal sheet having a tensile strength more than or equal to the tensile strength of the pair of rear frames 4. By this configuration, when an impact load from the rear side of the vehicle acts on the concave section 3 of the rear floor panel 2, the rear floor panel 2 can absorb collision energy in a principal way. Thus, the burden of absorption of collision energy by the rear frames 4 is reduced, and accordingly it becomes possible to reduce the wall thickness and the length of the rear frame 4 and a weight reduction of the entire car body structure is achieved.
