An apparatus and method for generating a shape model of an object and an apparatus and method for automatically searching for feature points of an object employing the same. The apparatus for automatically searching for feature points of an object includes: a shape model generation unit which generates a shape model including a mean model of an object, and statistical feature data of each feature point forming a mean shape, by training a plurality of training sets in which a plurality of feature points are labeled for the object; an initial position resetting unit which resets an initial position of each feature point of the mean shape according to a pose of an input image; and a feature point extraction unit which adapts the mean shape whose initial position is reset, to the input image, by using the statistical feature data of each feature point of the mean shape, and extracts feature points of the input image.
