Battaash (foaled 10 February 2014) is retired Irish-bred, British-trained Thoroughbred racehorse. A specialist sprinter who usually competed at the minimum distance of five furlongs, he was noted for his exceptional speed and unpredictable temperament. He won once from five starts as a juvenile in 2016 and was gelded in an attempt to improve his behaviour. In the following year he emerged as one of the best sprinters in the world, winning the Scurry Stakes, Coral Charge and King George Stakes before ending the season with an emphatic win in the Prix de l'Abbaye. In 2018 he won the Temple Stakes and recorded a second victory in the King George Stakes. As a five-year-old he won a second Temple Stakes and a third King George Stakes before producing his best performance of the season to take the Nunthorpe Stakes. In 2020 he was unbeaten in three starts, namely the King's Stand Stakes, King George Stakes and Nunthorpe Stakes. He was retired after two unsuccessful runs in 2021.

Battaash is a bay gelding bred in Ireland by the County Limerick-based Ballyphilip Stud. In October 2015 the yearling colt was put up for auction at Tattersalls and was bought for 200,000 guineas by Hamdan Al Maktoum's Shadwell Estate Company. Battaash was sent into training with Charles "Charlie" Hills at Lambourn in Berkshire.

His sire Dark Angel won four races including the Mill Reef Stakes and the Middle Park Stakes as a two-year-old in 2007 before being retired to stud at the end of the year. Dark Angel's other offspring have included Harry Angel, Lethal Force, Mecca's Angel and Persuasive. Battaash's dam Anna Law showed no racing ability, finishing at the rear of the field in all four of her races in 2012. Her grand-dam Noirmant was a half-sister to Braashee (Prix Royal-Oak), Ghariba (Nell Gwyn Stakes) and Adam Smith (Fort Marcy Handicap) and, as a female-line descendant of Pelting (foaled 1958) related to several other major winners including Moon Ballad, Bassenthwaite, Telescope and Awzaan.

Battaash made his first appearance in a maiden race over five furlongs on good ground at Bath Racecourse on 18 May and started a 14/1 outsider in a nine-runner field. Ridden by the apprentice jockey Michael Murphy he started poorly but took the lead a furlong from the finish and went clear to win "readily" by four lengths. The colt was then stepped up in class for the Listed Windsor Castle Stakes at Royal Ascot in June. He became highly agitated prior to the race and reared up in the starting stalls before finishing unplaced behind Ardad. Shortly after the race he was gelded.

Battaash recovered from his operation and returned to the track on 9 September in a minor race at Doncaster in which he led for most of the way before hanging to the right in the closing stages and finishing third behind Lost At Sea and Dream of Dreams. Two week later, under top weight of 133 pounds, he ran third in nursery handicap at Haydock Park. On his final appearance of the season, the gelding was stepped up to Group 3 class for the Cornwallis Stakes at Newmarket on 7 October. He briefly took the lead approaching the final furlong before being overtaken and beaten into third place by the fillies Mrs Danvers and Clem Fandango: as at Doncaster he compromised his chances by hanging badly to the right.

On his three-year-old debut, Battaash was partnered by Dane O'Neill and started at odds of 11/1 for the Listed Scurry Stakes at Sandown Park on 17 June. He started slowly but went to the front a furlong out and won from Koropick and the favourite Copper Knight despite displaying his old tendency to drift right in the closing stages. O'Neill was again in the saddle when the gelding was matched against older horses in the Group 3 Coral Charge over the same course and distance on 8 July. On this occasion he started 5/2 favourite against nine opponents including Goldream, Muthmir (2015 King George Stakes) Mirza (Prix du Petit Couvert) and Tis Marvellous (Prix Robert Papin). He took the lead soon after the start, opened up a clear advantage, and won in "impressive " style by three and a quarter lengths from Mirza. Battaash was moved up to Group 2 class for the first time when he contested the King George Stakes at Goodwood Racecourse on 4 August in which he was ridden by Jim Crowley. He went off at odds of 9/2 in an eleven-runner field which included Profitable (King's Stand Stakes), Marsha, Priceless (Temple Stakes), Take Cover (winner of the race in 2014 and 2016), Washington, D.C. and Ardad. Battaash tracked the leaders before accelerating into the lead a furlong out and winning by two and a quarter lengths from Profitable. After the race Charles Hill commented "He's a three-year-old who's improving and going through the ranks and this is another step up today. He's up against some proper sprinters there and he just travelled with such ease."

The Nunthorpe Stakes at York Racecourse on 25 August featured a much-anticipated clash between Battaash and the American filly Lady Aurelia. Battaash was among the leaders from the start but was unable to quicken in the closing stages and came home fourth behind Marsha, Lady Aurelia and the outsider Cotai Glory (also trained by Hills). In October the gelding was sent to France to contest the Group 1 Prix de l'Abbaye over 1000 metres at Chantilly Racecourse and started favourite in a thirteen-runner field which also included Marsha, Queen Kindly (Lowther Stakes), Signs of Blessing (Prix Maurice de Gheest), Profitable, Finsbury Square (Prix de Meautry) and Son Cesio (Prix du Gros Chêne). Crowley sent Battaash into the lead soon after the start and the gelding steadily increased his advantage to win "unchallenged" by four lengths from Marsha. Crowley commented "It was an unbelievable performance. He broke well and was absolutely winging; they just couldn't go fast enough for him. I ended up taking it up after a furlong and a half. With Battaash you're just a passenger, it's as simple as that."

In November, Battaash underwent an operation to correct a potential breathing problem caused by a trapped epiglottis.
