To provide a vehicle body rear part structure of a saddle-riding type vehicle which inhibits increase of the weight of a vehicle body frame and reduces attachment work hours of the vehicle body frame and may support a buffer while reinforcing a rear part of the vehicle body frame.SOLUTION: In a vehicle body rear part structure of a saddle-riding type vehicle, a buffer 29 is provided between a rear frame part 10B extending rearward from a main frame part 10A and a swing arm 23 of a rear wheel suspension device. The rear frame part 10B includes: a seat frame 11 extending rearward from the main frame part 10A; a sub frame 12 which extends rearward from the main frame part 10A below the seat frame 11, gets closer to the seat frame 11 toward a rearward direction, and is connected at a rear end part 12a to the seat frame 11; and a connection member 15 which connects the seat frame 11 with the sub frame 12 at the front relative to the rear end part 12a of the sub frame 12. An upper end part 29a of the buffer 29 is supported by the connection member 15.SELECTED DRAWING: Figure 2
