An electric suspension device, includes: an electromagnetic actuator which is arranged in parallel to a spring member provided between an unsprung member and a sprung member and produces a drive force; an information acquisition section which acquires acceleration information of the unsprung member and sprung member along the expansion-contraction axis; a damping force calculation section which calculates a target damping force; and a drive controller which performs drive control for the electromagnetic actuator using a target drive force based on the target damping force. The information acquisition section acquires a road profile signal based on the acceleration information concerning the front-wheel side. The damping force calculation section calculates the target damping force of the electromagnetic actuator provided at least on the rear-wheel side, based on a signal component within a rear-wheel-side vibration damping target frequency range, of the road profile signal based on the acceleration information concerning the front-wheel side.
