Septimus (4 April 2003 – 12 December 2010) was an Irish Thoroughbred racehorse and sire. In a racing career which was frequently interrupted by injury he won eight of his thirteen races between September 2005 and November 2008. He showed very promising form as a juvenile, winning the Beresford Stakes and finishing third when favourite the Racing Post Trophy and went on to win the Dante Stakes by eight lengths in an abbreviated three-year-old campaign. At four he won the Mooresbridge Stakes and was then stepped up in distance to take the Lonsdale Cup and the Doncaster Cup. In his final season he won the Curragh Cup and the Irish St. Leger, taking the latter event by thirteen lengths. He was rated the best horse in the world over extended distances in both 2007 and 2008. He was retired to stud but had fertility problems and died on 12 December 2010 after complications resulting from a gelding operation.
