An active suspension device includes: a preview sensor that detects a height of a road surface in front of a wheel; and an ECU that controls a stroke of a suspension to perform a preview control. The ECU includes: a front wheel preview control part that performs a preview control; a preview control success determination part that determines whether the preview control is successful; and a rear wheel control part that controls a stroke of a suspension of a rear wheel. When the preview control of the front wheel is successful, the rear wheel control part performs a preview control and a skyhook control of a rear wheel to control the stroke of the suspension of the rear wheel. When the preview control of the front wheel is unsuccessful, the rear wheel control part cancels the preview control of the rear wheel and perform the skyhook control of the rear wheel.
