Provided is an electric suspension device including an electromagnetic actuator that is provided between a body and wheel of a vehicle and generates damping force for damping vibration of the body. It includes: an information acquisition unit that acquires information on a wheel speed and a sprung speed of the vehicle; an estimation unit that estimates a stroke speed of the actuator based on the wheel speed; a determination unit that determines whether a wheel slip has occurred; and an orientation control unit that performs orientation control of the vehicle based on the sprung speed and the estimated stroke speed. When a wheel slip occurs, the orientation control unit performs orientation control of the vehicle based on a fixed stroke speed whose direction is the same as a direction of the sprung speed and whose magnitude is set at a predetermined fixed value, instead of the estimated stroke speed.
