A torque control apparatus includes: a flux linkage estimator estimating a variation of flux linkage based on a difference between a current temperature of a motor measured by a temperature sensor and a predefined reference temperature; a torque compensation value calculator calculating a torque compensation value corresponding to the current temperature of the motor based on the estimated variation of flux linkage; and a torque compensator compensating for an error of required torque of a torque command by applying the calculated torque compensation value in response to a change in temperature of the motor and outputting a final torque command including the error-compensated required torque to a current map of a motor controller.
