A vehicle includes a lower back panel, a rear side member, a gusset, a roof side rail, and a coupling member. The lower back panel has an outer panel and a lower back reinforcement, which is joined to the outer panel. The gusset is joined to both the lower back reinforcement and the rear side member. The coupling member is joined to both the rear end of the roof side rail and the lower back reinforcement. When viewed in the vehicle vertical direction, a region of the lower back reinforcement to which the gusset is joined overlaps with a region of the lower back reinforcement to which the coupling member is joined.
