Provided is a rear vehicle-body structure of a vehicle, capable of reducing vibrations transmitted from a rear wheel to a floor panel, while ensuring required performance for rear side frames and a cross member. The rear vehicle-body structure comprises a symmetric pair of frame members extending in a vehicle longitudinal direction along respective lateral sides of a rear of a vehicle body of the vehicle, and a rear-side rear cross member bridging the symmetric pair of frame members in a vehicle width direction, wherein an attachment portion between each of the frame members and the rear-side rear cross member provided with rigidity difference generation part to generate a rigidity difference between the frame member and the rear-side rear cross member.
