To provide an elevator door control device, a door opening/closing control method, and an elevator capable of preventing erroneous detection of an engaging position.SOLUTION: The door control device includes a control unit, a rotation detection unit, and a door moving speed detection unit. The control unit includes an engaging position calculation unit for calculating the engaging position where a car side door and a building side door are engaged with each other from rotation information about the rotation of a driving unit output from the rotation detection unit and speed information about the moving speed detected by the speed detection unit. Then, the engaging position calculation unit removes the rotation information and the speed information outside an engaging section estimated that the car side door and the building side door are engaged with each other according to mechanical specifications of the car side door and the building side door and calculates an engaging position within the engaging section.SELECTED DRAWING: Figure 8
