PROBLEM TO BE SOLVED: To provide a controller of an elevator door capable of reducing vibration and noise even if weight of a door panel is greatly changed and controlling opening and closing of the door without changing door opening and closing time. SOLUTION: This controller of the elevator door inputs a torque command obtained by controlling speed deviation between a speed command for the motor for opening and closing the elevator door and fed-back speed of the motor by variable gain into the motor to control opening and closing of the elevator door. This controller is provided with a gain setting part having a gain table for storing a plurality of gains having different size in advance, a speed deviation integrating part for obtaining an integrated value of an absolute value of the speed deviation per one opening or closing of the elevator door per story floor, and a gain change requiring or not determining part for changing to a gain second largest to the one at the time when the integrated value exceeds an allowance value defined in advance.
