Massive gravity based on the fractional action cosmology is discussed. In this new picture, the new theory requires the introduction, in addition to the ordinary graviton mass, fractional graviton masses which for a very low cosmic fluid density are different of zero. Their masses could be under certain restriction on the range of the parameters of the theory larger than 10(-4) eV even at large distances.
