The present invention relates to a grass protection mat which can be used in golf courses, grass fields, lawns and the like to protect grass while enduring pressure from being stepped on by people and loads from objects. The grass protection mat comprises: networked main body portions (10) in which hexagons are continuously repeated a tetragonal border (11) finishing the edge columns (20) vertically formed at each hexagonal corner of the main body portions wall support bodies (30) formed on the upper surface of the networked main body portions (10) so as to be lower than the columns upper protrusions (40) formed on the upper surface of the networked main body portions (10) so as to be higher than the columns and Y-shaped lower connectors (50) for connecting three columns (20) among six columns forming a hexagon at the lower ends of the columns (20) so as to meet at the center of the hexagon. The networked main body portions (10) are connected into a hexagonal shape at an upper portion, and the lower connectors (50) are connected into a hexagonal shape at a lower portion in such a way that the hexagon formed by the lower connectors (50) are offset relative to the hexagon formed by the networked main body portions (10), thereby effectively enduring pressure from being stepped on by people and loads from objects.
