In a remote parking device, a remote control receiver receives remote operation signals including remote parking commands of a subject vehicle from a plurality of remote controllers. A sensor information receiver receives sensor information including surrounding information obtained in a surrounding information sensor in the subject vehicle and vehicle information obtained in a vehicle information sensor in the subject vehicle. When the plurality of remote operation signals including the remote parking commands are received at the same time, a priority determination part determines priority of each of the plurality of remote parking commands included in the plurality of remote operation signals based on information obtained from the plurality of remote operation signals. A remote parking controller controls a remote parking of the subject vehicle based on the remote parking command having highest priority and the sensor information.
