Rancocas Farm was an American thoroughbred horse racing stud farm and racing stable located on Monmouth Road (County Road 537) in Springfield Township, Burlington County, New Jersey, Jobstown, New Jersey.
The farm was founded in the 1870s by the wealthy tobacco manufacturer Pierre Lorillard IV (1833-1901) who had a home in the town of Rancocas, now a part of Westampton Township, New Jersey. Lorillard built his stable into one of the premier thoroughbred breeding and training operations in the United States. Lorillard bred Parole, one of the three greatest runners of the 1870s. In 1881, Lorillard's horse Iroquois became the first American-owned and -bred horse to win a European classic race. Ridden by the champion English jockey, Fred Archer, Iroquois won the Epsom Derby then went on to also capture the St. Leger Stakes.
The site continues to operate as the Helis Stock Farm, and is run by Linda and Ed Lovenduski. The more than 2,000-acre (8.1 km2) farm includes a number of original Rancocas Stable-era buildings that can be seen from the roadside; including a training barn with 1,100 windows enclosing a half-mile oblong indoor track.
