An elevator control device, including an rpm detector, a landing-plate detector, and a controller, in which the controller includes a first remaining-distance calculating unit, which is configured to calculate a remaining distance to a destination floor as a first remaining distance based on the rpm, a second remaining-distance calculating unit, which is configured to calculate an ideal remaining distance from the detection of the landing plate to stop at a destination floor as a second remaining distance, an expansion-and-contraction amount estimating unit, which is configured to estimate an expansion amount of a governor rope from a difference value between the first remaining distance and the second remaining distance, and an expansion-and-contraction amount correcting unit, which is configured to correct the first remaining distance by adding a correction value calculated based on the estimated expansion amount.
