A rotary electric machine control device for controlling a rotary electric machine having multiple winding sets includes multiple inverter circuits, multiple power supply relays, and multiple controllers provided for respective systems. Each of the controllers is configured to monitor an abnormality of a subject system and an abnormality of a different system and is configured to turn off a power supply relay in the subject system when an abnormality requiring a power supply stop occurs in the subject system. Each of the controllers is further configured to acquire power supply relay information related to a state of the power supply relay of the different system through a signal line, and is configured to monitor the abnormality of the different system based on the power supply relay information.
