Provided is an elevator derailment detection device configured to detect disengagement of a vertically movable body to be guided by guide rails to be raised and lowered from at least one of the guide rails. The elevator derailment detection device includes: a conductive wire, which is provided in a hoistway in parallel to a direction in which the vertically movable body is raised and lowered; a magnetic field measurement device, which is provided to the vertically movable body so as to measure an intensity of a magnetic field generated by a current flowing through the conductive wire, and is configured to output the measured magnetic field intensity; and a controller configured to detect the disengagement of the vertically movable body from the at least one of the guide rails when the magnetic field intensity output from the magnetic field measurement device falls above or lower than an allowable range.
