Brooklyn "Brookie" Supreme (April 12, 1928 – September 6, 1948) was a red roan Belgian stallion noted for his extreme size. Although disputed, the horse may be the world record holder for largest (but not tallest) horse and was designated the world's heaviest horse. He stood 19.2 hands (198 cm (6 ft 6 in)) tall and weighed 3,200 lb (1,451 kg) with a girth of 10 ft 2 in (3.10 m). His horseshoes required 30 in (76 cm) of iron.
The horse was foaled on the Minneapolis, Minnesota farm of Earle Brown, who first exhibited it. Before becoming oversized, the stallion "had been Grand Champion of his breed in many state fairs". One of his great-grandfathers was another famous horse, Farceur 7332.
For much of his fame, Brooklyn Supreme was owned by a man named C. G. Good of Ogden, Iowa; Ralph M. Fogleman of Callender, Iowa partnered with Good and exhibited the horse around the US, charging spectators 10 cents to view the animal.
