In this paper, we study the superconvergence of the frictionless Signorini problem. When approximated by bilinear finite elements, by virtue of the information on the contact zone, we can derive a superconvergence rate of O(h 3 2 ) under a proper regularity assumption. Finally, a numerical test is g
