PROBLEM TO BE SOLVED: To provide a rubber crawler having a lug extending substantially parallel to the crawler width direction provided at the position corresponding to a core which is capable of enhancing the ride quality when a vehicle is traveling on a leveled land without impairing the durability of the rubber crawler. SOLUTION: In the rubber crawler comprising a crawler body 2 consisting of a rubber-like elastic body formed in an endless strip shape, a plurality of cores 3 embedded in the crawler body 2 in the longitudinal direction of the crawler, a tension body 4 embedded in the crawler body 2 along the longitudinal direction of the crawler, and a lug group which is protruded from the position corresponding to each core 3 on the outer circumferential surface of the crawler body 2 and consists of a plurality of lugs 5, 6 extending substantially parallel to the crawler width direction, a height fluctuating part 10 is provided on every lug or a part of the lugs out of the plurality of lugs 5, 6, in which the lug height in the center part of the crawler width direction is set to be smaller than the lug height at both ends in the same direction so that the lugs 5, 6 are not divided in the right-to-left direction in the crawler width direction.
