The invention relates to a deceleration assist device for a vehicle. A deceleration assist device is applied to a vehicle provided with a steering assist device that requests a driver to manually control when the vehicle speed or the lateral acceleration of the vehicle exceeds a corresponding control reference value in a hand-release mode in which automatic steering is performed in a steering mode, and that performs deceleration when the vehicle speed or the lateral acceleration of the vehicle exceeds the corresponding control reference value. The deceleration assist device includes a control unit that calculates a target deceleration on the basis of a traveling condition of the vehicle when deceleration of the vehicle is required, and decelerates the vehicle on the basis of the target deceleration. The target deceleration is calculated so that both the vehicle speed and the lateral acceleration of the vehicle do not exceed the corresponding control reference values.
