The invention relates to a rail profile defect identification method and system, and relates to the technical field of rail maintenance. The method comprises the steps that a reference point serves as an original point, a track profile defect recognition coordinate system is established, and the reference point is determined according to the position of a track gauge measuring point on the inner side of a track profile; according to the rail profile defect identification coordinate system, standard rail profile coordinate values and actual rail profile coordinate values are obtained; and comparing the actual rail profile coordinate value with the standard rail profile coordinate value to obtain defect degrees of the rail profile at different positions. The reference point for track profile defect recognition is determined according to the position of the track gauge measuring point on the inner side of the track profile, and the reference point is the track gauge measuring point and is accurate and easy to recognize. The rail profile defect identification coordinate system is established according to the reference point, the rail profile defect degree is measured by using the difference value between the actual rail profile coordinate value and the standard rail profile coordinate value, the rail profile defect can be accurately identified, the repair amount can be better determined, and a rail profile defect repair scheme can be better formulated.
