An elevator control apparatus which can improve car position detection accuracy without increasing the number of sensors is disclosed. The present control apparatus is the one which, upon receiving a detection signal that a position detection sensor (9) which is installed on a car (1) outputs when the position detection sensor detects an object to be detected (10) which is installed in a hoistway, corrects a position of the car calculated on the basis of a pulse signal that an encoder (8) which rotates in accordance with ascending and descending of the car (1) outputs, in accordance with a position of the object to be detected (10), has a storage device which stores data on the position of the car (1) calculated prior to a time point when the detection signal is received from the position detection sensor (9), and a correction amount of the position of the car (1) is calculated on the basis of a communication delay time and the data which is stored in the storage device, and the position of the car (1) is corrected in accordance with the correction amount.
