A clutch control device is provided for a 4-wheel drive vehicle. The clutch control device includes a 4WD control unit that controls the engagement and release of a friction clutch and a dog clutch which are arranged separately in the two paths. The 4WD control unit has a synchronization speed control unit, and at a time of transition from a disconnected, two-wheel drive mode, in which the friction clutch and the dog clutch are released, to a connected, four-wheel drive mode, in which the friction clutch and the dog clutch are engaged, the synchronization speed control unit reduces a synchronization speed of the dog clutch more during vehicle deceleration than when the vehicle is not decelerating.
