A system and method for monitoring a torque in a hybrid electric vehicle are capable of preventing misdiagnosis in determining whether there is an abnormality in generating torque commands. Accordingly, torque monitoring may be accurately performed. The method includes comparing a command torque limit value determined by adding a compensation value to a request torque to be monitored with a sum of command torques for each power source, among power sources in the hybrid electric vehicle, to determine whether there is an abnormality in generating a torque command for a power source in the hybrid electric vehicle. The method also includes limiting the compensation value added to the request torque to be monitored to calculate the command torque limit value to a driving system limit value at vehicle level.
