Authorized (foaled 14 February 2004) is an Irish-bred and British-trained Thoroughbred racehorse, winner of the 2007 Epsom Derby.

Funsie was owned by the Irish jockey Mick Kinane, who is one-third of the partnership which bred Authorized.

He was sold as a foal for 95,000 guineas to Tony Nerses at Tattersalls Newmarket, England sales in November 2004[2] and returned there in October 2005 as a yearling to be bought by the Newmarket trainer Peter Chapple-Hyam for 400,000 guineas on behalf of the Kuwaiti businessmen and racing partners Saleh al Homaizi[3] and Imad al Sagar.

"[5] A month later, on 21 October 2006, Authorized returned to Newbury to contest the Group One Racing Post Trophy over one mile.

Dropped back in the field early on, he came to join the leaders inside the final two furlongs and won comfortably.

His winning margin has not been bettered since Slip Anchor won in 1985 and in a faster time than either Motivator in 2005 or Sir Percy in 2006.

[10] He was provided with a pacemaker, Champery, to give him a strong pace in an effort to test the stamina of his closest expected rival, George Washington, but despite beating George Washington he finished second to Notnowcato, who was switched to the stands side of the course by Ryan Moore to exploit the faster ground there.

[13] Authorized stood as a stallion for the Darley organisation at Dalham Hall Stud near Newmarket before moving to the Haras de Logis in Normandy in 2014.
