Altisidora (1810–1825) was a British Thoroughbred racehorse and broodmare best known for winning the classic St Leger Stakes in 1813. Bred, trained and raced in Yorkshire she won two of her three races as a two-year-old in 1812. She was unbeaten for the next two seasons, winning three races including the St Leger at Doncaster as a three-year-old and four as a four-year-old in 1814. In her final season she won four of her eight races including a Great Subscription Purse at York, the Fitzwilliam Stakes at Doncaster and a King's Plate at Richmond. She was retired to stud, where she had some impact, being the grand-dam of Ralph, the winner 2000 Guineas and the Ascot Gold Cup. Altisidora died in 1825 at the age of fifteen.

Altisidora was a chestnut mare with a white star and two white feet bred by Richard Watt of Bishop Burton in Yorkshire. She was sired by Dick Andrews, a grandson of Eclipse whose other progeny included the 2000 Guineas winner Cwrw, the Oaks Stakes winner Manuella and the successful stallions Tramp and Muley Moloch. Her dam Mandane has been described as one of the best broodmares of the early 19th century and was also the dam of Manuella, and the Chester Cup winner Brutandorf. Mandane is regarded as the foundation mare of Thoroughbred family 11-g. Altisidora was trained throughout her racing career by Tommy Sykes and ridden in most of her races by John Jackson.
