An apparatus and a method for detecting a driver's hands-off may include a torque sensor that detects a torque signal generated from a steering wheel of a vehicle, a vibration generator that generates a reference vibration to the steering wheel of the vehicle, a filter that extracts a torque signal of a vibration frequency band from the detected torque signal, and a controller that activates the vibration generator when a change rate of the detected torque signal exceeds a threshold value and determines whether the driver's hands-off occurs based on a change of the torque signal extracted by the filter.
