Preakness Stables was a Thoroughbred horse racing stable established by Massachusetts businessman Milton H. Sanford in Wayne, New Jersey at what today is the corner of Valley Road and Preakness Avenue.
Milton Sanford named one of his horses Preakness who won the first running of the Dinner Party Stakes and for whom the Preakness Stakes is named.
In addition to the New Jersey stable, Milton Sanford owned the 544-acre (2.20 km2) Preakness Stud Farm in Lexington, Kentucky. One of their stallions at stud in Kentucky was Virgil, who sired Kentucky Derby winners Hindoo, Ben Ali and Vagrant, plus Preakness Stakes winner, Vanguard, and the champion 2-year-old colt, Tremont.In 1881, the sixty-eight-year-old Milton Sanford sold the Kentucky Preakness Stud to Daniel Swigert who renamed it Elmendorf Farm.
Under trainer Edward Feakes, Preakness Stables won the Preakness Stakes twice. Their first victory came in 1890 with Montague and in 1895 with Belmar who also won the Belmont Stakes.
