A clutch control device for a four-wheel drive vehicle is provided, the device being able to suppress the elevation of the temperature of the oil supplied to a friction clutch during two-wheel drive travel when the friction clutch is released. The clutch control device is configured such that the device is mounted in a four-wheel drive vehicle provided with a dog clutch (8) and an electronic control coupling (16) housed in a coupling case (25); when a disconnected, two-wheel drive mode in which the dog clutch (8) and the electronic control coupling (16) are released is selected, a passage opening (25e) provided in the coupling case (25) is closed and lubrication oil (O) is retained in an oil chamber (25c) defined with respect to a clutch chamber (25b) that houses the electronic control coupling (16). When oil stirring conditions are met thereafter, the passage opening (25e) is opened and the lubrication oil (O) is allowed to flow into the clutch chamber (25b) from the oil chamber (25c).
