An apparatus for compensating for a column torque in an MDPS (Motor Driven Power Steering) system including: a column torque sensor configured to sense a column torque applied to a steering shaft and output a column torque signal; a vehicle velocity sensor configured to sense a vehicle velocity; and a controller configured to receive the column torque signal to extract a vibration frequency of steering vibration caused in a steering apparatus, determine a filtering gain based on the vehicle velocity sensed by the vehicle velocity sensor, and filter the column torque signal such that a column torque signal corresponding to the extracted vibration frequency is attenuated to an attenuation length which is determined according to the filtering gain.
