The electromagnetic suspension apparatus includes: an electromagnetic actuator provided in parallel with a spring member between a vehicle body and a wheel of a vehicle and configured to generate driving force involving vibration damping of the vehicle body; an information acquisition unit configured to acquire, through a high-pass filter, time-series information about a stroke position of the electromagnetic actuator; and an ECU configured to calculate target driving force of the electromagnetic actuator and use the calculated target driving force to execute driving force control of the electromagnetic actuator. The ECU corrects the target driving force such that when the stroke position on the basis of the high-pass-filter-processed time-series information, from which low-frequency components (steady state deviation) have been removed, is present in a neutral region including a neutral position, spring force of the spring member is made weaker than when the stroke position is present in a non-neutral region.
