A center nock for a bow string of an archery bow includes a substantially C-shaped body portion having spaced ends extending substantially linearly therefrom. The ends are formed with first respectively axially aligned half groove portions adapted for engagement with the bow string. A cross support bar is secured to the spaced ends, the support bar including second respectively aligned half groove portions which cooperate with the first respectively aligned groove portions to form a pair of closed apertures fully encircling the bow string.
