A seat control device has an input unit for performing at least one of an operation to incline and move a first seat, and a drive control unit for at least one of inclining and moving the first seat based on an output of the input unit. The seat control device has an open/close detection unit for detecting an opened or closed state of a door for getting on and off to and from the first seat, an angle detection unit for detecting an angle of a backrest of the first seat; and a seating detection unit for detecting presence/absence of seating at a second seat positioned behind the first seat. When the open/close detection unit detects that the door is in the opened state, the angle detection unit detects an angle of a backrest of the first seat. When the detected angle is larger than a predetermined angle, the seating detection unit detects the presence or absence of seating at the second seat. The drive control unit is driven based on the detection of absence of seating to return the backrest of the first seat to an original orientation.
