A normal projective non-Gorenstein log-terminal surface S is called a log del Pezzo surface of index three if the three-times of the anti-canonical divisor −3KS is an ample Cartier divisor. We classify all log del Pezzo surfaces of index three. The technique for the classification is based on the argument of Nakayama.
