A braking force control device is provided which has a control unit that controls an upstream braking actuator that generates a common upstream pressure for four wheels and a downstream braking actuator that individually controls the braking pressure supplied to each wheel using the upstream pressure. The control unit controls the upstream pressure so that the braking pressure of the front wheels is permitted to be higher than a lock pressure of the rear wheels but does not become higher than a lock pressure of the front wheels, and suppresses an increase of the braking pressure of the rear wheels so that the braking pressure does not become higher than the lock pressure of the rear wheels, in a situation where the upstream pressure can be supplied to each braking force generating device but the braking pressure of any one of the wheels cannot be decreased.
