To effectively improve resistance of a rear side frame against load input due to collision of a vehicle with simple configuration.SOLUTION: A vehicle body rear part structure comprises: a rear side frame (10) extending in a cross direction of a vehicle body (1) on a vehicle width direction outer side in a floor part (2) at a rear part of the vehicle body (1); a front cross member (30) connected to a first connection part (31) of the rear side frame (10); a rear cross member (40) connected to the rear side frame (10) by a second connection part (41) which is positioned on a rear side with respect to the first connection part (31); an arm fitting part (17) provided on the rear side frame (10); and a reinforcement member (60) which extends in a vehicle width direction in a cross section of the rear side frame (10), and reinforces the arm fitting part (17). The reinforcement member (60) is located at a position between the first connection part (31) and the second connection part (41) in the cross direction of the vehicle body (1).SELECTED DRAWING: Figure 1 【課題】簡単な構成で、車両の衝突による荷重の入力に対するリアサイドフレームの耐性を効果的に向上させる。【解決手段】車体（１）の後部のフロア部（２）における車幅方向の外側で車体（１）の前後方向に延在するリアサイドフレーム（１０）と、リアサイドフレーム（１０）の第一連結部（３１）に連結されるフロントクロスメンバ（３０）と、第一連結部（３１）よりも後側に位置する第二連結部（４１）でリアサイドフレーム（１０）に連結されるリアクロスメンバ（４０）と、リアサイドフレーム（１０）に設けられるアーム取付部（１７）と、リアサイドフレーム（１０）の断面内で車幅方向に延在してアーム取付部（１７）を補強する補強部材（６０）と、を備え、補強部材（６０）は、車体（１）の前後方向における第一連結部（３１）と第二連結部（４１）の間の位置に配置される。【選択図】図１
