The invention relates to a rainwater grating which comprises a frame (1) and a grate (2) settled on the frame, the frame comprising a flow-through opening (4) and a flange (6) circumferentially surrounding the flow-through opening, the flange having a top end (9), bottom end (10), outer rim (7) and inner rim (8). To achieve a better than normal water receptivity for the rainwater grating, the flange (6) comprises at least one rainwater groove (11) arranged to guide water arriving at the top end (9) of the flange through openings (17 to 19) of the grate (2) to the flow-through opening (4) of the frame. <IMAGE>
