Alhaarth (24 February 1993 – 29 July 2015) was a champion Thoroughbred racehorse and sire, bred in Ireland, but trained in the United Kingdom and Dubai during a racing career that lasted from 1995 to 1997.

Alhaarth was a bay horse with a white blaze standing 16 hands high,[1] was bred in Ireland by his owner Hamdan Al Maktoum's Shadwell Stud.

He showed his inexperience ("ran green") but took the lead inside the final furlong to win by a neck from the future Classic winner Mark of Esteem.

[13] Alhaarth began 1996 as the short-priced favourite for both the 2000 Guineas and the Derby although Hern was reported to be concerned by the colt's lack of physical growth.

He started 1/2 favourite for the Craven Stakes over a mile at Newmarket, but after taking the lead, he was caught in the closing stages and beaten a neck by Beauchamp King.

[16] He was held up in the early stages, but when asked to challenge he was unable to reach the leaders, and finished fourth, six lengths behind Mark of Esteem.

Ridden by Richard Hills, Alhaarth led from the start and stayed on strongly to record his first victory in almost a year, beating the 1995 winner of the race, Shaanxi, by one and a half lengths.

Twelve days later, he traveled to Ireland to win the Group Two Budweiser American Bowl International Stakes, taking the lead a furlong out to beat Gothenberg by a length.

[22] His next two starts were disappointing: he finished last of the nine runners in the Celebration Mile in August and a remote third, beaten more than 18 lengths behind Pilsudski in the Irish Champion Stakes.
