Provided is an abnormality determination device of a vehicle including an engine and a first motor that is configured to output a torque to an output shaft of the engine, the abnormality determination device determining an output abnormality of dropping output of the engine in the vehicle. The abnormality determination device has an abnormality determination unit that determines that an output abnormality of the engine has occurred when an actual torque that is estimated, based on a torque of the first motor, as a torque actually output from the engine falls below a lower limit of an allowable range for a target torque to be output from the engine, and when an amount of increase in a rotational speed of the engine is smaller than a threshold value for misdetermination suppression, which is a threshold value that is larger as the target torque is higher.
