A four-wheel drive vehicle are provided which enable enhancement of responsiveness to switching from a two-wheel drive state to a four-wheel drive state. A four-wheel drive vehicle includes a driving force transmission and cut-off apparatus that enables cut-off of transmission of a driving force from an engine to a propeller shaft, a driving shaft that rotates under a tuning force of the propeller shaft, a pair of hydraulic clutches and each disposed between the driving shaft and a corresponding one of rear wheels, and a control apparatus that controls a hydraulic unit that supplies hydraulic oil to the hydraulic clutches. In shifting the two-wheel drive state to the four-wheel drive state, the control apparatus controls the hydraulic unit such that a higher priority is given to supply of the hydraulic oil to first hydraulic clutch than to supply of the hydraulic oil to second hydraulic clutch.
