Deep Sensation (6 July 1985 – 25 November 2003) was a British Thoroughbred racehorse who competed under National Hunt rules. He ran in six consecutive Cheltenham Festivals and is best known for his win in the 1993 Queen Mother Champion Chase. In his first three seasons he was campaigned in hurdle races, recording his most notable success in the 1990 Tote Gold Trophy. When switched to larger obstacles he was one of the leading novice steeplechasers of 1991/1992, winning the Lightning Novices' Chase and the Nottinghamshire Novices' Chase. He reached his peak in the following season, when he took the H & T Walker Gold Cup, the Queen Mother Champion Chase and the Melling Chase. He never won another major race but recorded two minor wins and was placed in several important chases over the next two years. He was retired from racing after a narrow defeat in the 1995 Melling Chase after winning thirteen of his forty-nine races and being placed on twenty-one occasions. He died in November 2003 at the age of eighteen.
