Disclosed in the present invention are a fuel rod clamping ring and a fuel assembly supporting grid. The fuel rod clamping ring is arranged in a supporting grid to clamp a fuel rod inserted into the supporting grid. The fuel rod clamping ring comprises a clamping ring body, a plurality of clamping portions arranged on the clamping ring body in a protruding mode so as to clamp the fuel rod penetrating through the clamping ring body, and a plurality of connecting portions arranged on the clamping ring body and connected to the supporting grid. According to the present invention, the clamping portions of the fuel rod clamping ring protrude out of the clamping ring body, facilitating formation of stable surface contact between the clamping portions and the fuel rod, so that local abrasion of the surface of the fuel rod by the clamping portions can be reduced; the clamping ring can be integrally placed in the supporting grid only by connecting the connecting portions to the supporting grid, so that the clamping ri
