Pierre J. Lorillard IV (October 13, 1833 – July 7, 1901) was an American tobacco manufacturer and thoroughbred race horse owner.

Lorillard had inherited 13,000 acres (53 km2) around Tuxedo Lake, which he developed in conjunction with William Waldorf Astor and other wealthy associates into a luxury retreat.

Although his horse "Parole" finished fourth in the 1876 Kentucky Derby, it went on to race with considerable success both in the United States and in Europe.

Lorillard had other successes in England, notably with the horse named for the actor David Garrick, which won the 1901 Chester Cup ridden by American jockey, Danny Maher.

Beyond his interest in racehorses, Lorillard was a scholar who financed the Central American expedition of the French archaeologist Désiré Charnay and his publication of "The Ancient Cities of the New World.

[citation needed] Through his daughter's second marriage, Lorillard was an ancestor of the present Baron Revelstoke and of the heir apparent to the earldom of Oxford and Asquith.
