John Albert Morris (July 29, 1836 – May 25, 1895) was an American businessman widely known as the "Lottery King" and a prominent figure in the sport of thoroughbred horse racing.

A native of New Jersey, he benefited from a large inheritance and added substantially to his fortune through a majority interest in the Louisiana State Lottery Company.

As a boy, he traveled to England, under the charge of Richard Ten Broeck, when he put Prior and other horses on the English turf.

[2] Morris inherited his father's 25,000-acre (100 km2) ranch in Gillespie County, Texas, fourteen miles (23 km) from the town of Kerrville, where he established a horse breeding operation.

At one point in time, Morris owned nine "superbly equipped establishments in America and Europe," including in New Orleans, Louisiana, Throggs Neck, New York, three properties in Boston, Massachusetts, Bar Harbor, Maine, Gillespie County, Texas, and in Hanover, Germany.
