A seat control device has a first input unit for performing an operation of moving a first seat to a front side or a back side, a first drive control unit for moving the first seat to the front side or the back side based on an output of the first input unit, a second input unit for performing an operation of moving a second seat, positioned behind the first seat, to the front side or the back side, and a second drive control unit for moving the second seat to the front side or the back side based on an output of the second input unit. A control unit is arranged for prohibiting movement of the first seat and the movement of the second seat from being simultaneously carried out when the operation to move the first seat to the back side is performed at the first input unit and the operation to move the second seat to the front side is performed at the second input unit.
