Exeter Racecourse is a thoroughbred horse racing venue located near the city of Exeter, Devon, England. Locally it is known as Haldon racecourse because of its location on top of the Haldon Hills. At 850 feet (260 metres above sea level, it is the highest course in the UK. Until the early 1990s it was officially known as Devon and Exeter.

On 1 November 2005 racehorse Best Mate died at the course of a suspected heart attack whilst competing in the William Hill Haldon Gold Cup.

Horse racing has been part of Exeter's heritage since the middle of the 17th century, one of many racecourses created due to Charles II's love of the sport, and there have been claims that the racecourse is one of the oldest in the country. Horse racing rules were standardised after the Jockey Club was formed in 1750. A race was written about by Louisa Graves in 1819, and there were records of meetings at the course in 1804, probably earlier.

Devon and Exeter celebrated its bi-centenary on 8 October 1969, but there are records of racing at Haldon from 1738. In 1823, the course, which had been situated on common ground until the Enclosure Act, came into the ownership of Sir Lawrence Park (later Lord Haldon). He increased the number of racing days and the prize money. In 1826, for example, there were the Silver Tureen and Devonshire Stakes, won by horses owned by Lord Palmerston, there was a £100 purse put up by the City of Exeter and Ladies' Purse of £80. In May 1828, the 'Exeter and Plymouth Gazette' reported that, "The racecourse at Haldon is to be much improved previous to the next meeting. A race stand on an extended plan is being erected." A racecard of 1831 refers to an old and a new course.

Almost until 1900, Haldon continued as a flat racing venue, although hurdle races were run occasionally. Devon and Exeter steeplechases were set up in 1898 when the Haldon Race Club was formed.

In June 1904, in 'Devonia', the official publication of the United Devon Association, Cecil Clapp commented that, "While the county does not boast any large racemeeting, there is much genuine sport obtained in steeplechasing at Torquay, Newton, Totnes, Exeter (Haldon), Tiverton, South Molton, Plymouth, Devonport and other smaller towns."

The course was popular during the early 19th century, attracting entries from all over the country. By 1850, the popularity of National Hunt racing had waned and William White's gazetteer claimed that it was "little used". It popularity increased again over the following years, although there was a pause in racing during World War II. The course has been known variously as Haldon racecourse by locals due to its location, Devon and Exeter until the 1990s and more recently Exeter Racecourse.

In October 1972 there was an application to stage motor racing at the course, but it was turned down by Devon County Council.
