Rock Sand (1900-1914) was a bay or brown Thoroughbred race horse bred by Sir James Miller at his Hamilton Stud in Newmarket. The colt was sired by Sainfoin, out of the dam Roquebrune by St. Simon. He was a beautifully conformed horse and possessed great courage during his racing career.[1]

In 1903, Rock Sand won the English Triple Crown when he won the Epsom Derby, 2,000 Guineas, and the St. Leger Stakes. In 1906 when Rock Sand was sold for £25,000 for breeding purposes to the American August Belmont, Jr. who sent him to his stud farm in Lexington, Kentucky. There, he sired Mahubah (1910), the dam of Man o' War. He sired Damrosch, winner of the 1916 Preakness Stakes and was the damsire of Preakness winners Broomspun (1921) and Coventry (1925).

Among Rock Sand's other progeny was Tracery (born 1909) who won the St. Leger Stakes for August Belmont, Jr. and Museum National D'Histoire Naturelle in Paris, France.
