A driving force distribution control apparatus for a four-wheel drive vehicle includes a basic distribution determination device and a servo controller. The basic distribution determination device is configured to determine basic distribution of a driving force to secondary drive wheels in accordance with the driving force and driving conditions of the vehicle. The basic distribution determination device includes a tire force limit determination device and an arithmetic device. The tire force limit determination device is configured to calculate a tire required acceleration in accordance with the driving conditions of the vehicle and configured to output a basic distribution adjustment signal having a characteristic that gradually decreases a ratio of the basic distribution for the secondary drive wheels to zero in a transient region in which the calculated tire required acceleration is lower than a predetermined threshold value.
