Grand Flaneur (1877-1900) was an outstanding Australian Thoroughbred racehorse and sire, who won nine successive races, including the AJC Derby, the Victoria Derby and the 1880 Melbourne Cup, before he retired undefeated. He had won races over distances ranging from five furlongs to three miles. He was the Leading sire in Australia in 1895 and was close to the top of the list for a decade.
