A slope-descending speed control device 10 for a vehicle configured to control a vehicle deceleration so that an actual vehicle speed conforms to a target vehicle speed in accordance with a target deceleration Gxbt of a PID feedback control executed in accordance with a difference between a target vehicle speed Vxt and an actual vehicle speed Vx. In a situation where an actual vehicle speed is higher than a target vehicle speed, with a component in a hill-descending direction of gravitational acceleration of the vehicle at a time point when a condition for starting a slope-descending speed control is satisfied being a reference gravitational acceleration Gxd0, when a difference between a component Gxd in a hill-descending direction of gravitational acceleration and the reference gravitational acceleration Gxd0 is between upper and lower reference values, a target deceleration Gxbti of the integral term is not integrated to restrain its increase.
