Refuse To Bend (17 March 2000 – 10 February 2012) was a Thoroughbred racehorse and sire.

Refuse To Bend was a bay horse with a white star and white socks on his hind legs bred by his owner the Swiss businessman Walter Haefner at his Moyglare Stud Farm near the town of Maynooth, County Kildare, in Ireland. He was sired by the Champion Sire Sadler's Wells. His dam, Market Slide was a daughter of Gulch, the 1988 U.S. Champion Sprint Horse. Market Slide had previously produced the Melbourne Cup winner, Media Puzzle,^[2]

Refuse To Bend made his debut in August 2002 in Gowran, Ireland at Gowran Park, winning a Maiden race by four lengths. He then moved up to compete against top-level colts in the National Stakes at the Curragh Racecourse. A win in that race and another in the following spring's 2,000 Guineas Trial at Leopardstown Racecourse made him a contender for the 2003 British Classic Races.

Ridden by regular jockey Pat Smullen, Refuse To Bend won the first Classic of the 2003 season, the 2,000 Guineas at Newmarket Racecourse. Still undefeated, he started 11/4 favourite for the 2003 Epsom Derby as the betting favourite but finished thirteenth behind winner Kris Kin. Refuse To Bend went on to win the Group III Desmond Stakes but was unplaced in two other races. At the end of the year, he was sold to Sheikh Mohammed bin Rashid al Maktoum.

At age four, under trainer Saeed bin Suroor and jockey Frankie Dettori, Refuse To Bend came back to win two Group I races. He defeated Warrsan in the Eclipse Stakes at Sandown Park and in the Queen Anne Stakes, he beat both the top mare Soviet Song and the 2003 Breeders' Cup Mile champion, Six Perfections

Refuse to Bend was retired at the end of the 2004 racing season. He stood at Darley's Kildangan Stud, in Kildangan, County Kildare, Ireland and Whitsbury Manor Stud.^[2] Later he was transferred to Normandy.^[2] His first crop of foals were born in 2006.
