Witch Elm (1904–1923) was a Thoroughbred racehorse owned by the William Hall Walker and trained by Jack Robinson.

[2] Amongst her other races were a fifth place in the National Breeders' Produce Stakes at Sandown and a third place in the Lancashire Breeders' Produce Stakes at Liverpool.

[3] As a three-year-old she easily won the 1000 Guineas from Fragility[2] after starting the 4/1 favourite,[4] but could not repeat this classic winning form over longer distances.

[5] Witch Elm did not produce any top racehorses, but some of her descendants became classic winners in Brazil.

[1] In 1919 Witch Elm produced the filly Lady Clarence, who was sired by Queen Alexandra Stakes winner Royal Realm.
