The present disclosure relates to a device and method for generating steering reaction torque. In providing a reaction torque to a steering wheel of a steer-by-wire steering system, the device may determine a target frequency according to the rotational speed of the wheel, generate a filtered rack force signal excluding a cutoff band including the target frequency from the rack force signal, generate a target reaction torque signal based on the filtered rack force signal, and generate the reaction torque based on the target reaction torque signal. Therefore, it is possible to improve the steering feeling of the SBW steering system by providing the steering wheel with reaction torque from which unnecessary vibration components such as shimmy and judder are removed.
