A golf putting aid is provided that includes first and second attachment structures. Upper and lower alignment members are each disposed between and attached to the attachment structures. The alignment members are also vertically aligned to define a vertical plane which is perpendicular to a putting surface. The putting aid also includes at least one longitudinal support member disposed between and fixedly attached to the attachment structures, and a target attached to the first attachment structure, such that the target defines an opening that is at least as large as a regulation size golf ball.
