The present disclosure relates to an apparatus for correcting an offset of a resolver of an environment-friendly vehicle. The apparatus includes a resolver offset correcting error determining unit configured to determine whether a resolver offset correction error occurs, by determining whether an engine clutch is released and a torque command of a motor. The apparatus further includes a motor speed change value calculating unit configured to calculate a change value of a speed of the motor when it is determined that the resolver offset correction error occurs and a controller configured to extract a resolver offset change value by using a resolve offset change value table for the change value of the speed of the motor.
