  We investigate the Einstein-Podolsky-Rosen (EPR) steering and its criticality
in quantum phase transition. It is found that the EPR steerability function of
the ground state of XY spin chain exhibits nonanalytic feature in the vicinity
of a quantum phase transition by showing that its derivative with respect to
anisotropy parameter diverges at the critical point. We then verify the
universality of the critical phenomena of the EPR steerability function in the
system. We also use two-qubit EPR-steering inequality to explore the relation
between EPR steering and quantum phase transition.
