Slip Anchor (1982–2011) was a British Thoroughbred racehorse best known for winning the 1985 Epsom Derby by seven lengths. After showing some promise as a two-year-old, he showed substantial improvement in the spring of 1985, winning the Derby Trial at Lingfield Park Racecourse by ten lengths before recording a rare start-to-finish win in the Derby. He was rated the best racehorse in Europe in 1985. His subsequent career was disrupted by injury, and he finished second in his other three races before being retired to stud. He had some success as a breeding stallion and died in 2011.
