Coastal Bluff (foaled 19 April 1992) was a British Thoroughbred racehorse. First trained by David Barron in Yorkshire he finished second on his only start as a juvenile before winning two minor races in the following year. In 1996 he emerged as a highly successful sprinter with wins in the Stewards' Cup and the Ayr Gold Cup before his season was ended by injury. He returned as a five-year-old to dead-heat for the Nunthorpe Stakes despite his bridle breaking just after the start. He developed various training problems, failed to win in two races in 1998 and was sold at the end of the year. He remained in training for four more years but won only two minor races from 37 further starts before his retirement in 2002.
