The invention discloses a sheep face alignment and recognition method and system based on key point detection, and the method comprises the steps: collecting sheep face data, which comprises images of which face key points are shielded and images of which face key points are not shielded; marking sheep face positions and non-shielded face key point positions in each image in a manual mode, and dividing data into a test set and a training set; detecting to obtain the specific position of the sheep face part in the image; constructing a key point detection model, and detecting face key points; when it is detected that the face key points are not shielded, sheep face alignment is conducted through a sheep face alignment algorithm with the center of the connecting line of the two eyes as the benchmark; and when it is detected that the face key points are shielded, sheep face alignment is carried out by adopting a sheep face alignment algorithm with a four-point connecting line crossing reverse extension center as
