A braking force control apparatus has an upstream braking actuator for generating an upstream pressure common to four wheels, a downstream braking actuator individually controlling braking pressures supplied to braking force generating devices of the wheels using the upstream pressure, and a control unit. When the downstream braking actuator is abnormal and the upstream pressure can be supplied to the braking force generating devices, but a braking pressure of any one of the wheels cannot be normally reduced, the control unit selects higher one of the target braking pressures of the left and right front wheels and higher one of the left and right rear wheels, determines lower one of the two selected target braking pressures as a backup target upstream pressure, and controls the upstream braking actuator such that the upstream pressure becomes the backup target upstream pressure.
