An object of the present invention is to obtain an electromagnetic suspension apparatus capable of meeting a request to improve ride comfort irrespective of a magnitude of a spring constant preset in a spring member. The electromagnetic suspension apparatus includes an electromagnetic actuator that generates a driving force related to vibration damping of the vehicle body, an information acquisition unit that acquires information on a stroke position of the electromagnetic actuator, and an ECU that calculates a target driving force of the electromagnetic actuator and controls a driving force of the electromagnetic actuator using the calculated target driving force. When the stroke position acquired by the information acquisition unit is in a neutral range including a neutral position, the ECU corrects the target driving force so as to reduce a spring force related to the spring member as compared with when the stroke position is in a non-neutral range.
