Phantom (1808 – 1834) was a British Thoroughbred racehorse and sire. In a career that lasted from April 1811 to April 1813 he ran ten times and won seven races. In the summer of 1811 he proved himself one of the best British colts of his generation, winning the Derby on his second racecourse appearance. He continued to race with considerable success for two more years, mainly in match races. He was retired to stud in 1814 and became a successful sire of winners before being exported to Mecklenburg in 1832.
