Thormanby is a village and civil parish in Hambleton district of North Yorkshire, England. It lies on the A19 approximately halfway between Easingwold and Thirsk and about south east of the county town of Northallerton.
Thormanby (1857–1875) was a British Thoroughbred racehorse and sire. In a career that lasted from May 1859 to July 1861 he ran twenty-four times and won fourteen races. He was regarded by experts as one of the outstanding horses of his era.
After winning nine races, including the Gimcrack Stakes at York as a two-year-old in 1859 he won the Epsom Derby on his first start of 1860. Although he failed to reproduce his best form in the autumn of his three-year-old season he returned in 1861 to win his first four races including the Ascot Gold Cup.
At the end of the 1861 season he was retired to stud where he sired the winners of many important races. His grandson, Bend Or, became the direct male ancestor of most modern Thoroughbred racehorses.
