We present a theoretical prediction of the new edge barriers for Abrikosov vortex penetration into polycrystalline superconductors. The traditional Bean-Livingston surface barrier is governed by the strength of the external field. Edge barriers in polycrystalline superconductors are also governed by the external field as well as by the anisotropy ratio, grain-coupling strength and grain size. We support our theory with concrete calculation of the critical current density in both high- oxide and superconductors.
