St. Giles (horse)
 St. Giles (1829 – circa 1839) was a British Thoroughbred racehorse and sire. In a career that lasted from October 1831 to July 1835 he ran eleven times and won five races. After showing little form as a two-year-old he made marked improvement to win his first three races of 1832 culminating with a highly-controversial success in the Epsom Derby. His only subsequent wins came in two minor races in 1835 and he was eventually sold and exported to stand as a stallion in the United States.
