Abstract : Let k be an algebraically closed field. Chambert-Loir proved that thé etale fundamental group of a proper normal rationally chain connected variety over k is finite. We prove that the fundamental group scheme of a proper normal rationally chain connected variety over k is finite too. In particular, the fundamental group scheme of a Fano variety is finite.
