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 unusual 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.
