A driving force control apparatus (1) is configured to determine a front and rear wheel drive distribution which is a ratio of driving force between front wheels (21) and rear wheels (22) in a four-wheel drive vehicle, and configured to calculate positive or negative standard driving acceleration (XG) obtained based on an input amount from a driving force instruction device (42) of the vehicle and a vehicle speed, and based on the standard driving acceleration (XG), switch between and perform dynamic load ratio distribution control that determines the front and rear wheel drive distribution in accordance with a dynamic load ratio distribution curve (L1) which is a curve of a dynamic load ratio applied to the front wheels and the rear wheels with respect to the standard driving acceleration (XG), and rear wheel-biased distribution control that determines the front and rear wheel drive distribution in accordance with a rear wheel-biased distribution curve (L2) which increases a rear wheel drive distribution compared to the dynamic load ratio distribution curve.
