Abstract: In this paper, the Chow groups of projective hypersurfaces are studied. We will prove that if the degree of the hypersurface is sufficiently high, its Chow group is ``small'' in the sense that its formal tangent space vanishes. Then, we will give an example in which the formal tangent space is infinite dimensional.
