Provided is a passenger-conveyor step-chain monitoring system capable of monitoring elongation of a step chain without adding a special device. The passenger-conveyor step-chain monitoring system includes a monitoring unit configured to monitor elongation of a step chain attached to a step of a passenger conveyor based on a result of detecting the step by a sensor provided to detect an absence of the step. With this configuration, it is possible to monitor elongation of the step chain without adding a special device.
