Unfuwain (5 March 1985 – 16 January 2002) was an American-bred, British-trained Thoroughbred racehorse bred and owned by Hamdan Al Maktoum.

Unfuwain was a strongly-built, 16.1 hand[2] bay horse, bred in Kentucky by his owner Hamdan Al Maktoum.

[4] Two weeks later he move up in class and recorded an eight length win in the Group Three Chester Vase, taking the lead in the straight and finishing "unchallenged".

After a brief break he returned in the Princess of Wales's Stakes and, facing older horses, produced his best performance, taking the lead two furlongs out and pulling away to win by fifteen lengths from a field which included Canadian International Stakes winner Infamy, and Breeders' Cup Classic runner-up Ibn Bey.

[10] In his final race of the year he finished fourth in the Arc, beaten just over a length behind Tony Bin, Mtoto and Boyatino.

[13] Three weeks later in the Jockey Club Stakes at Newmarket Unfuwain went clear a quarter mile from home and did not have to be put under pressure to record a one length win over the Derby runner-up Glacial Storm.

[14] Sheriff's Star, who went on to win both the Coronation Cup and Grand Prix de Saint-Cloud later that summer, was beaten a further six lengths in fourth.

In January 2001 he was awarded the title of Leading British-based Stallion for the previous year by the Thoroughbred Breeders' Association.
